I have the Abrams-Allen family tree compiled in 1953 by John Abrams in front of me finally. That didn't take long! I don't think this will answer your question completely. It is somewhat confusing because I don't know which Henry or Gabriel you are referring to because there are three Henry's and three Gabriel's back to 1720. There is a Mary b.1834 d. 1855 who is the sister of a Gabriel b. 1831 d. 1855. Henry b. 1720 had a daughter Rhoda b.1755 d.? who also had a brother Gabriel b.1750 d. 1841 who served in the 8th Pennsylvainia Regiment. Her dates are very hard to read. Mary would also have had an aunt named Rhoda. Let me know if I have completely confused you. Good luck!
