Still running comparisons on my Genesis results versus my Gedmatch results. Discovered one interesting item today. A match with a known 5th cousin once removed changed slightly between the two databases. The match still shows up as schematically one match but the values show a break about in the middle. My match and I are related on my Rawlins line but the match has two Rawlins lines with her ?x great grandparents marrying descendants of two siblings (one of the siblings is my ancestor). Interesting to find the slight difference. It doesn't affect our overall match and I can see that I need to pay attention on Genesis to close together matches of less than 10 cM that I might have ignored in Gedmatch unless there was a reason to look at it.
Is Genesis more accurate than Gedmatch? I am beginning to explore that thought. I thought there wouldn't be much difference between the two but it does appear that slight differences are occurring and I am rerunning my larger matches and making a second record on each datasheet in excel for these matches.

Genesis (upgrade from Gedmatch)
All of my kits have been converted to Genesis now and about half of them are research only so do not form part of any searches except my own. I have 21 matches with my Living DNA kit to other Living DNA kits on Genesis. Only three have a longest length of 12 cM or greater and only one is particularly significant at 25.7 cM. I match this individual at Ancestry and FT DNA. Like myself, they have tested at a number of sites but I can not yet locate her in my tree although I suspect endogamy in this case and the match is likely much further back than the length of the match would indicate.
I need to look at the other kit that that I have which was tested at Living DNA to see how many Living DNA matches there are.
2nd kit of interest: 16 matches with just one with a longest length of 12 cM or greater. At 13.9 cM it does not catch a great deal of interest from me as I really do not look a lot at matches of less then 15 cM. This match is on chromosome 17 between 5836860 and 10226337. Looking at my list for Chromosome 17 this is one that is only shared by this one sibling.
I always look at all of my matches with the thought that knowing I have 23,000 matches at Ancestry in their database of over 11 million (0.2% of their database) and that I have only 245 matches which are 4th to 6th cousin or less (0.002% of their database), I probably shouldn't expect to have too many matches in databases that are much smaller!
At FT DNA I have 2082 matches and 190 are 3rd to 5th cousin or less and their database is less than one million. Say it was one million then I have 0.2% of their databases as total matches and 0.02% of their database as 3rd to 5th cousin or less.
At 23 and Me which has a database of over 5 million I have 998 matches (0.02% of their database). I have 332 matches that are third to sixth cousin or less (0.007% of their database). I tend to know who these individuals are if they match me at least 0.50% but not always.
I am not that really surprised that I have only sibling matches at Living DNA. My father was an only child so no first cousins. His mother only had half-siblings so do have some half-first cousins. His father had eleven siblings but very few nieces and nephews except his eldest sister had a large family but thus far none have tested. My mother was born in Canada. She had just one brother and he did not have any children. Her father was virtually an only child as none of his full siblings survived to adulthood. He did have a half-sister but none of her descendants have tested. Her mother did have four siblings but thus far none of their descendants have tested as they would be my second cousins.

52 Ancestor Challenge
Would dearly like to do another 52 Ancestor Challenge but it will not happen this year. I shall aim towards doing that 52 Ancestor Challenge beginning in 2019. It will look at the 4x great grandparents of our son in law. All 64 of these 4x great grandparents are known so I shall combine a few of them. Amazingly he never has a duplicate set until one gets back further in time. When I first started this project I had the impression that many many descendants of these early French Canadian settlers had many lines in common. Indeed they do but their families were so very large that often enough in the case of our son in law he is descended from a number of children of the same couple way back in the 1600s and 1700s. The story of the French Canadians is a very important one in Canadian history and it is good that so many are involved in putting together these descendants of that early group. The priests were so very helpful as well carefully recording the birth parishes in France for the many couples who married in Quebec City in the 1600s and they continued with that careful reporting up to the present. Such a wonderful set of historical documents on the early history of Canada.
With three grandparents born in England and the fourth although born in Canada descendant of individuals also born in England, my footprint on this side of this ocean is incredibly small as just my mother, her father and his mother were born in Canada; all the rest were born in England as far back as I have been privileged to trace their lines.
My husband, on the other hand, has a much deeper footprint with his own lines being part of the very early migrations to the New England Colonies/New Holland Colonies dating back to the 1620s.
As I think about all of this history at my fingertips, I must admit some regret at not taking up the mantle of genealogical research much earlier. My husband (his forays in genealogy go back 50 years looking at his Kipp family in particular) started to attend the Ontario Genealogical Society Meetings, Ottawa Branch, in the early 1980s but I simply did not want to get involved in research. My mother was busy going to the Family History Library and collecting information on her family lines which she mentioned in her letters to me so the need to do so never really occurred to me. My mother was still alive when I first went to England in 2001 and I mentioned to her the feeling of being at home in London. At that time, she did mention that she thought the father of her grandfather Buller was from London. My mother passed away several months after that. It took several more years for me to put together my thoughts on that trip to England (I was still working fulltime and that pretty much along with my husband and children occupied my life at the time) and the idea of doing research. It was my cousin George DeKay though who really accelerated the idea of doing genealogy. He wanted a bio for my Pincombe family (my mother was a Pincombe) as an early settler in Westminster Township in 2003 for publication in 2005 (gave me two years to do it!). He was editing the history book for this Township and told me that he had 40 bios to write and I needed to do this one for him. If I did not do it then my cousin would and that cousin believed that my grandfather had a grocery store on Wharncliffe Road. Well that pretty much did it; that Pincombe was my uncle not my grandfather who was a farmer and I did want the history to be right!
Now as I ponder paths backwards in time, the idea that it had to be right bringing me into genealogy, I have to chuckle. I try to have it right; I love it when autosomal DNA matches shows me that indeed I am on the right path but getting it right is not as easy as I may have thought at that time. You can get the early generations pretty well right on but further back even the most exhaustive searches can, on occasion, miss interesting details that would have taken you another path. DNA helps so much with all of that. It would be wondrous if everyone would take their results into Gedmatch I must admit.

200 Ancestor Hints (Shaky Leaves at Ancestry)
It is very interesting testing at Ancestry when you have fifty years of research on your family lines particularly if those family lines have deep American Colonial roots. That is the case for my husband and he now has 200 Ancestor Hints (and 705 fourth cousins or less). These hints are very interesting as one of them is a third cousin, 36 are 4th to 6th cousins and the remainder (163) are 5th to 8th cousins (indeed he does have some that are named as 8th cousins and 8th cousins once removed/twice removed). The third and fourth to sixth cousins were all readily known to him (they all have trees online and only 3 of the 4th to 6th cousins are private.
The fifth to eighth cousins are perhaps the most interesting. A number of these have more than one hint (i.e. he is descended from more than one set of common ancestors) and for a few there are three sets of common ancestors (he has a number of loyalist lines in New Brunswick). An amazing number of these lines are in the United States including descendants of the Loyalist lines.
Perhaps the most interesting for someone who has done genealogical research for fifty years is the verification of all that research. American records are scant in the period of the Revolutionary War (War of Independence) so linking back in this time period can be a very difficult process using various records and finding others who may have bible records has been a real asset to his research. He has been able to add quite a number of lines to his tree down to the present.
It is also very pleasant to find these results transferred to GedMatch as he has an ongoing project looking at phasing his grandparents DNA. Unfortunately his brother died in 1996 so he does not have any DNA for a sibling. His father died in 1945 and his mother in 2000 so again no DNA for either of them. A number of second cousins have tested which has been handy but it is amazing how quickly the amount of shared DNA diminishes.
For myself, I have acquired another Ancestor Hint bringing me to a total of 18 and for my siblings I have 16, 15 and 15 hints. Some of these we all share (I have four of us on Ancestry so three of these matches are us matching each other, we have four fourth to fifth cousins that we all share, we have four fifth to seventh cousins that we all share thus giving us twelve in common). Three of us share three in common, two of us share two in common. There are three that are shared by one only of us giving a total of 21 different Ancestor Hints.
Compared to my husband I have very few Ancestor Hints but our ancestries are very different. With his overwhelming American Colonial ancestry going back to the 1620s/1630s and early 1700s plus one 2x great grandmother and parents from Norfolk, England and one set of great grandparents directly from Germany, Ancestry has proven to be the best place to test for him although his matches at FT DNA and My Heritage are also interesting.
Gradually I am acquiring new matches as more and more people in the British Isles test. My own ancestry is totally British Isles going back as far as I can trace and indeed only England as the Irish/Scot ancestry in terms of actual names other than Routledge remains hidden to me. DNA may reveal it as my maternal grandmother's mother's line remains unknown to me other than she was likely born in Birmingham in the mid 1800s.
Living DNA may prove interesting for both of us as my husband has so many dissenters from England in his early colonial ancestry and with both my brother and I testing there as well I am hopeful that many many people in the British Isles have tested as well and will take part in matching.

Contacts at 23 and Me
My results are just a couple of days old at 23 and Me and already I have had two contacts (one I initiated and one to me). For the one it is my Blake line in Hampshire and the relationship is very ancient going back to my 11x great grandfather (I have one Blake marriage which brings two lines together at my 9x great grandparents giving a little extra boost to the genes I guess!) and the other is a mystery at the moment although we share surnames in both Hampshire and Warwickshire. So a little sleuthing to come on those lines (3rd cousin is the indication). I have 919 matches at 23 and Me but mostly in the distant category. No close relationships but 1 2nd to 4th unknown, 5 3rd to 5th cousins, 101 3rd to 6th cousins, with the remainder being more distant. About 1/3 to 1/2 are public matches. There are many many with American ancestry. My contacts were both from Australia with ( like me) 100% British Ancestry.
There are also quite a few matches with people having 100% Irish ancestry. Perhaps I will solve that elusive great grandmother after all with a match. I have one particularly good match on the X chromosome which bears further research and it is a public match. I have written and will see what happens there. This person has ancestry in Northern Ireland which is the likely place for my great grandmother to have been located or at least her family as she was born in Birmingham. The nice part is my mitochondrial DNA can be used as well. This particular grouping that I have is found principally in Northern Ireland and in Argyllshire/Ayshire Scotland. We are ancient to the British Isles (H11a2a1) although I note that the greatest frequency for our haplogroup H11a2 is The Netherlands which I think is one of the migration points out of Ukraina following the Last Ice Age. Because my matches are also in Sweden I was suspicious that they had taken the northern route to get to Scotland but a southern route across Europe into the British Isles (via Doggerland) is also very conceivable with people spreading out from a common migration route. All of this is so exciting and the area is under water (the North Sea flooded Doggerland thousands of years ago as the ice sheets retreated).
So all in all, another interesting result for me and I have taken all three autosomal results into Gedmatch and I am a perfect match for myself. Always rewarding given my science background to see the duplication of results from the same person. Since I have been involved with DNA from almost the beginning of my genealogy research days, I adhere very strongly to the principal that you really cannot do genealogy without both paper trails and DNA trails. It is amazing to be able to prove your research in such a scientific way.
