I think I might have found some information for you.All the information I am about to tell you I got off of the web site www.familysearch.org.
I did a search for Wilson Abraham, and I found a Wilson born about 1841 (exact date unknown)in Ohio, died about 1903 (exact date unknown).It has 3 brothers listed, Joseph born about 1743 in Iowa, John born about 1844 in Iowa, and James born about 1845 in Pennsylvania.It has there parents listed as Lot Abraham born about 1775 in Pennsylvania, died 1852, married about 1819 in Iowa to Mrs. Mary Abraham.
The name of Lot Abraham sounded very familiar to me, so I then did a search on Lot Abraham, and found him listed as being the son of Benjamin Abraham and Elizabeth Goheen.When I saw these names, I thought it was safe to say that there is a good chance that we are distant relatives based on the information that I have.Benjamin is my GGGGGgramdfather, and he was the father of my ancestor, Benjamin Jr, and your's Lot Abraham.Benjamin Sr.'s parents were Noah Abraham born about 1700 in Wales, died on May 29, 1758 and Mary Wynne born about 1708 in Pennsylvania, died about 1758.Noah's parents were Morgan Abraham born about 1660 in Wales, died about 1712 in Wales and Sarah, born about 1668 in England.I don't have anything further back on the Abraham line, still searching.Mary Wynne's parents are Jonathan Wynne born about 1669 in Wales, died 1-29-1720 or 1721 in Pennsylvania and Sarah Graves, born October 1659 in CT, and died 2-27-1743 or 1744 in PA.Jonathan Wynne's parents were Dr. Thomas Wynne born 7-20-1627 in Wales, died March 1691 or 1692 in PA (famous quaker, came to America on the ship "Welcome" with William Penn, and was one of the founders of Philadelphia) and Martha Elizabeth Buttal born 1627 in Wales, died 1670 in PA.
I have a lot more information about Dr. Thomas Wynne, and would share any information that you are interested in.
If you find out that the information I found online is wrong, and your Wilson and my Benjamin are not related, please let me know, and I can do some further searching to assist you.
