So i have my main Gedcom tree (Tree1)exported from Ancestry, and some of these people have already been added to wikitree.
I have exported my wikitree as a gedcom (Tree2), and this contains the wikitree ids.
What I would like to do is match each wikitree person in Tree2 to the person in Tree1, and then add the wikitree id to the correct place in Tree 1.
Does anybody have a way of doing this ?
