Hi there is an autobiography of Jacob Young (Martha's Father), written 1857 or 1860. Jacob Young Autobiography of a Pioneer or something like that. He was a Methodist circuit preacher who reported to Bishop Asbury.
I may be able to find the obituary of JA Shaw, seems like I had it. Do you have any more info of his preaching, where, what church, his sermons, etc.? I am a Shaw (descendedn of Agnes Ellen Shaw), is this still valid contact info? Please contact me. email@example.com
