Kelly- I searched my tree out and could not find any Thomas Adams of 1790 in PA. There still could be a limb out there that is not listed... I did search any Adams who Died in Indiana and found one male Samuel Adams and several women. Unfortunately Samuel Adams had no offspring named Thomas. I did find some marriage records (see below- copy & pasted)There is one Thomas F. Adams of 1790 (might be the marriage date?), maybe the spouses name will give you another direction to search. Good luck!
