I have a (living) uncle that I recently discovered that he is not only a uncle by marriage, but is also an 18th cousin. He does have a profile on my family tree (made by me, btw). Not terribly long ago I found out (via WikiTree) that he is also related to me through my mother's side of the family. I followed the very long trail/connection given and he is my 18th cousin. However, when I click on his name, currently, this information doesn't come up, which seems odd to me. Is it okay to list his name and WikiTree I.D. if he's living ?
