Hi! I have 2 sources that give Simon's mother's maiden name as Wykoff: one is the "Biographical Record of Bureau, Marshall, Putnam & Stark Counties, Illus." (IL) pub. 1897; p.515 & the other is "Biography and Reminiscences of West Jersey Twp." in the Stark Co., IL History. There is information on the Addis fmily in: "Records of the Cummins, Addis & Carhart Families of Warren Co.,NJ" byG. Wyckoff Cummins, Belvidere, NJ, 1942.
