Abraham Neff, son of Jacob and Eva Katherine (Flora) Naff, b. in Pa. 22 Feb. 1758; died in Preble Co., Ohio ca. 1813. According to one report, "he married in Franklin, Co., Pa, Katy Saylor, sister of Mary Saylor who married Sebastian Naff, brother of Jacob Naff, Sr." (18, pg. 52). Dr. J. M. Henry provided some date on Daniel Seilor (Saylor) and his family. He mentioned Bostian Naff as son-in-law, but no mention of Abraham Naff. He also gave the birth date of Mary and of Catherine. Catherine was born, according to his record, in 1736, and was married long before her father moved to Frederick Co., Md. (13, pg. 86). If the data in these reports are true, then Catherine (assumed to be Katy) would have been 22 years older than Abraham.
