With respect to the parents of Sarah Ross, I obtained the information from a Carroll County (Ohio) newsletter published in the 70s if I remember correctly, which specifically referenced the baptism date of Janettje VanDerBeek, and mentioned the name of Abraham Ross. I don't know if Abraham was from Edward's family, although I think it's likely based on location. I will scan it into my tree and copy you when I get back home from my Christmas vacation. This is one branch of my family I'm very interested in. I tried to contact the publisher of the story in the newsletter, but I think she died.
