Not sure this is the right place to put this but here goes ........
Some of you may have come across my posts about my search for my maternal grandmother who came from Switzerland (she is no longer alive).
I may have found some living descendants and wondered whether DNA testing would pinpoint that we have the right family?
I have no idea how specific it can or cannot be - can anyone help me please?
The relative I have found would be my mother's cousin.
Thanks.
