DNA is not really in dispute because 5 people have triangulated atDNA markers at the same genetic distance from Birmingham POPPLEWELLs. 4 descendants on proven on paper, including myself, and the genetic cousin I am working with to solve her ancestry. This person was adopted in the US. We recently found, through DNA, her half-sister she didn't know about. She also matches the group, hence we now know who their biological father is. His Canadian ancestry can be followed on all lines back to 1800 still in Canada, well before the genetic distance for the markers on the UK, except for one 7 y.o. boy coincidentally arriving from Birmingham in 1874. The DNA is important in that is a control and could have only been realistic provided by this child. The story in Birmingham is not straightforward, as we are finding out. Detailed matching of DNA actually puts the POPPLEWELL father on one particular branch, as one of four sons to Nathan POPPLEWELL. One of whom kept two families - his wife and his mistress. Two weren't yet married; two were. They lived in the same area of Birmingham as the GROVES/DAVIS/PENRICE families. Maybe one was "BIRCH".
Joseph PENRIGHT & Elizabeth CARRINGTON are the parents of a child named James PENRIGHT on the BC. I am not convinced, for the various reasons given in this forum, he is necessarily the same as James PENRICE sent to Canada. Too many options remain.
I quite like the BIRCH becoming PENRICE idea, but it doesn't help. I will pass on to the cousin to see if she will apply for the Susannah BC, which I almost sure will be the same couple as identified for James PENRIGHT. I would be happier if Elizabeth CARRINGTON wasn't a 13 year old girl for this scenario.
My thanks to everyone. I am closing this thread now to relay findings to my genetic cousin.
