Humbled again by the Genealogy process. I was wrong about James S Murphy being the father of John Murphy b. 1755-1826. I have emailed with a Murphy cousin who has done extensive research. There exists a DNA test that proves my John is NOT THE SON OF James S. Murphy. So I apologize for the misinformation, my enthusiasm exceeded my knowledge. I hope I haven't misled anyone else's research.
I was reassured however, that although James S. is not an ancestor, the others on the descendancy list were correct except for James S.
