Hi everyone, looking for some help with a close match of my mum's.
My mum has tested with My Heritage, one of her closest matches is with an RM at 223.3 cM.
RM was adoped, RM's son manages the accounts and he states that RM knows who his birth mother is and knows her ancestry. When comparing RM's birth mother's ancestry with my own maternal side there is a common ancestor, but it's quite far back for a match of 223.3 cM.
The common ancestors are my mum's 3x great-grandparents. This doesn't seem right for a match of that size, but I could be wrong.
It's entirely possible that my mum matches RM elsewhere (even on his birth father, of which they have no information), her ancestry is heavily localised. In fact, my mum and dad share common ancestors as well, and I have found matches with myself who match my mum and dad on separate chromosomes.
Any help appreciated.
EDIT: I suppose it's possible that we share more than one common ancestor making the match with RM appear closer than it really is. I know it's relatively rare, but I have already experienced this with another match (not related to RM) where they match my mum on one chromosome and my dad on another and they don't share mutuals.
