Reading through this abstract gives you a slightly different impression of the will. Was Archibald Forrester's wife a Routledge or was it that his sister had married a Routledge or both? He mentions that Sibilla Routledge is a relation to him.
Also the statement that there was only one Archibald Forrester buried at Stapleton in this time period and that was in 1767. So I have perhaps misread the abstract in the long run.
There are two baptisms for Grace Routledge in the 1740s and I will have to look at both of them once again.
