Having too much data

Working on all of this data I realize I am trying to do too much and really need to whittle down the number of items that I do each day as it conflicts with my writing. I have sufficient data to do whatever I want to do really and in some ways again a great deal more than I actually need. Working through the matches has shown me that. I did start out small with this whole process but my siblings were so very willing to contribute to the study and as the number of companies increased so did the volume of my results. For what I want to do the companies that provide me with the most information are Ancestry (although no actual results unless you do PRO which shows you a more in depth view of the matches between you and between shared matches; so interesting but too time consuming for the moment). Because of the volume that I already have I am not going to sign up for that just yet. Then FT DNA is also a really good setup for matches and it was these two that I originally tested my siblings at or they tested themselves. Then 23 and Me came into view and I tested myself and then let everyone know the results and my older brother Doug thought he would like to do that so already had two spare email addresses as he didn't want to do anything with it just wanted me to tell him what was in it. So I agreed to test him and sent the kit to him from the one email address and he filled it in and sent it back. The results came and he was very pleased with the results and I collected matches and this was long ago before you could have family groups so gradually the number of accounts that I needed to open and close; keep email accounts for grew. He then told my younger brother and he decided he would like to have those kind of results so I tested him with my second spare email address and again sent the kit to him and then he returned it and I told him the results and started collecting more data although he was very very like my older brother (very similar in his matching so just a second match with pretty much the same people. I did consider deleting that second account the last while since I am trying to trim down but then he passed away and it was just nice to still have that little bit of memory of him. Although 23 and Me no longer provides a breakdown of matches so I am into that account less and less and it also creates problems which I need to try and resolve today to get back my access to my two yahoo accounts. I have two step verification which is working but doesn't get me where I need to be. We will see how that goes; I will try again in the day time hours. I actually have two accounts at 23 and Me (about ten years apart I think) and the results are duplicate but I decided to do that and then I have the 23 and Me Plus as well which is interesting especially testing on the newer chip. I was into the Yahoo accounts just a couple of months ago and it was fine so will try again. I am very careful to have different passwords for everything; somewhat complicated but it works. 

So can you have too much data? Probably not you just have to do what I am slowly doing which is downsize any data that doesn't really add very much new - it is complicated as I whip back between accounts in particular between Ancestry and the other accounts as all the trees are on Ancestry or My Heritage. But Ancestry has a huge American content and surprisingly for me with just a very little step on this continent, three grandparents born and raised in England, my father born in England coming to Canada with his parents as a child of 9 in 1913 and the remaining grandparent was my mother's father who was born in Canada, his mother was born in Canada and along with my mother they are my three only Canadian born ancestors. So one wouldn't expect to see matches deep into the colonial past of the United States except I am. Huge matches really in the 40+ cM range. Just not expected except this is a pile up area as it is referred to by genealogists - some areas where one's ethnicity dominates the genetic passage of that particular length of gene and this particular length has three such areas; one larger (about 20 cM) and the other two smaller perhaps a couple of centimorgans each. But it does mean that the actual look of the length is much smaller on say Ancestry where TIMBER extracts this common ethnic area from the match giving you this true match. Interesting really but I do not need to contemplate all of that for my study - it is just interesting. So flipping back to trees shows me that so many of these matches (and I only extracted about half of them and they are all mine; no one else matches me on this particular Chromosome 15) in the maternal length of the chromosome. Sometimes  my interest in medicine creeps in and I am tempted to see what has been located on that chromosome gene-wise but I haven't done so; I think my interest in medicine is slipping away. 

Today I plan to work on Chromosome 14 and it is already set up and it is where my older brother and I share matches with a lot of people having Jewish ancestry. We are often said to be third or fourth cousins but that is likely impossible as I am pretty much complete back to the 5x great grandparents and corresponding with a couple of people has shown that the link maybe as far back as 8x great grandparents. Somewhat fascinating in itself. It is a small match chromosome - just 27 matches in total over all the databases but I am looking forward to studying more closely the matches at Living DNA which I have collected. It is now a couple of months since I did that collection and I need to check one of these days on the new matches. But if I have Jewish ancestry it is likely located in my maternal line by the matches and possibly from Somerset. My familiarity with Jewish history in Britain is pretty thin so I do not know if that would be anticipated. But just two of us really share these matches (my older brother and myself) and we also show 0.2% Jewish ethnicity which is within the range of error so very very small but the matches can be larger than you would think. Interesting really especially given the theory particularly expressed during the latter part of the 18th century that the original inhabitants of Britain were one of the Lost Tribes of Israel. Fascinating really but I am not getting that too much. I added my older brother's yDNA to one of the University databases there when they were collecting his haplogroup as it is said to be ancient to the British Isles (Deer-Hunters was the name given to them by Ethnoancestry (and yes I did test him there and he found that really exciting). It gave us a lot to talk about all those years when I became involved all because our mother who had spoken to both of us about her idea of testing the family DNA.  My older brother then invited my younger brother to become involved just to keep us altogether I think but the interest there was not very high and eventually he asked me not to send him all that material which I did not although I probably slipped up sometimes. 

Also I want to rake the front lawn as I did complete the laneway yesterday and it is pretty much free of leaves. Once I have that done I think I might put the car away as I do not want to have to scrape the windows. Plus I have one leaky tire which I have to fill every two weeks or so and it would be warmer in the garage to do that for sure. It is a great gadget I saw advertised on TV because the mechanism of my going to a garage and filling a tire could not seem to get into my mind. Purchasing this marvelous pump was the greatest idea and it works beautifully. It is very noisy so always do it in the mid morning when it probably does not disturb anybody. It is very efficient. You just set it for 36 and it fills the tire to 36 and shuts off. They did everything to find that leak but it remains a mystery. For a small amount I bought that and a plug as the actual machine doesn't come with the plug for the electricity to recharge it but only a car charger. Works perfectly though and is pretty fast although as I said the noise is deafening. 

Late today; I actually slept in. Tea all drank and must do my solitaire puzzles and then breakfast and on to the day.
