The first challenge was to join a collaborative genealogy site.
They suggested Geni, Wikitree, Familysearch and MyHeritage. I am on all 4. I am not sure why MyHeritage counts, it is not exactly a collaborative genealogy site? OneGreatFamily is a collaborative genealogy site but wasn't included (its not free, which may be one reason for not including it.) I also have a tree there, but dont currently subscribe/maintain it.
Geni is still my favorite of the collaborative genealogy sites. I use Geni daily. If you are also on Geni, I would love to hear from you and what are relationship is, and maybe you can help me find a path to AJ!
One of the ways I like to use Geni to find possible relationships with DNA matches.
In the past few weeks I have had several cousins contact me on Geni, including some fairly close ones.
Here is my profile at Geni.
