A Skeleton in the Closet

My First Cousin Once Removed (FCOR) is really getting into family history.  Since I last had an Ancestry.com account, amazing research tools have become available.  My FCOR brought to my attention to an ancient skeleton in the closet of one of my ancestors.  The skeleton came to light during her research.

This ancestor had a child out of wedlock. She and her father sued for seduction and got child support. In those days wives and children were considered "chattels" or property of the head of household.  So the ancestor sued for "seduction" and her father sued for "trespass for seduction." I didn't realize that men were held accountable for children out of wedlock in the old days as they are now. The interesting thing about the case is that Abraham Lincoln was the attorney for our ancestor plaintiffs.

Here is the link to my pedigree chart on Familysearch, the church website: https://familysearch.org/. It only takes a minute to register for your own account.  Type in your name and me as your Mom and you will be hooked up to all the information I have entered.  Using logic and the information I have given you about the attorney, see if you can figure out which ancestor was represented by Lincoln.

DON'T post the ancestor's name if you comment.  After all, how would any of us like a serious mistake posted on a blog for the whole world to see?  If you figure it out, send me an email.
