It occurred to me that if the other tree owner says OH's grandmother is her first cousin 3x removed then the tree owner's 3xg-grandparent(s) who are the grandparents of OH's gran would have been on her tree on Ancestry and would have shown up had OH looked at her tree. We know who three of the four grandparents are (her father was illegitimate) so there's a good chance (if OH looked at the tree!) he would have noticed the name(s) as he is very familiar with this part of his tree.

So, the chances are she doesn't have a tree we can view on Ancestry! So, I will have to get him to ask her exactly how she is connected to his grandmother (he asked her that already, but her answer was insufficient and unhelpful!)

Thanks for all your help, Kate and Phoenix.
