I have Zachariah of James and Keturah line in Barnesville: 1830 census Barnesville, Warren Twp, Belmont, Ohio p. 209 There are other Barnes on the same page - they have not been identified 1860 census Barnesville, Warren Twp, Belmont, Ohio p. 668 From Colonial Families of Anne Arundel County, Maryland: "In 1850, Zachariah Barnes, age "60" was living with Thomas N. Hayes in Warren Township, Belmont Co., OH (Bemont Co. dwelling 289, fam. 295). In 1860, Zachariah was listed as age 72, and was still living with Thomas N. Hayes." [I read Thomas' middle initial as "H" not "N".] I have no information as to the WIlliam, etc. mentioned.
