Closest living Lincoln descendant

[Juan Marrero]

Without invading anyone's privacy who doesn't want ot be identifed as such, I wonder who is the closest living collateral descendant of President Lincoln. There appears to be no direct descendant and his only sister died in childbirth, so the remaining candidates would have to be descendant's of any cousins he may have had. I'm sure that l'm not the only one who wished that there were linear descendants. Funny thing, there is a young man in my office who says he is a direct descendant of Jefferson Davis. I guess in the War to Pass on the Genes, it was no contest.

The bloodline of very great men/women (at least based on anecdote) seems to run dry qickly...Washington, Shakespeare.
