I don't have a thing on the Rinehart ancestry for Peter Aaron. I had to go back and look, it's been a while since I've worked on the family tree. Maybe I'll see what I can find after the holiday.
I am also reminded, I don't know if any of the Rinehart researchers here were keeping track of descendants of Abraham Rinehart & C. Bretz; Elizabeth Rinehart & Levi Ewing; Adelma Ewing & George Allen Lippincott; Frank Wilfred Lippincott & Edith Clyde Woolley; Agnes Leon Lippincott & Frank Summers Culbertson. If so, an update: daughter of the last couple listed, Mary Alice Culbertson, b. 01 May 1921, d. 13 Jun 2005 in Niagara Co., NY. (This was my mother-in-law.)
