I'm glad you responded.I'm sorry for the delay in my response.I have done quite a bit of research on the Formans in Hampshire Co., but have not exhausted all the avenues. Most of the Formans had left Hampshire Co. by the 1790s for Kentucky.
After Benjamin Forman Jr. of Hampshire Co. died, his wife Elizabeth remarried to Edward Guphill.The Edward and Elizabeth Guphill and Elizabeth's son John Forman moved to Craven Co., South Carolina by the time they convey Hampshire Co. land in Jun 1769:
Edward Guphill and wife Elizabeth Guphill, the former wife of Benjamin Foreman the younger of the county of Frederick now deceased and John Foreman oldest son and heir of said Benjamin, now all of the county of Craven Co. SC to William Foreman of Hampshire Co., 400 acres on the Wappacomo and being tract No. 26.[Deed of lease and release, signed 22 & 23 Jun 1769, recorded 14 Nov 1769. Hampshire Co., West Virginia Deed Book 2, deed 156 & 157, page 289-293] This lot was conveyed by a Fairfax Northern Neck grant to Benjamin Foreman Jr. in 1749.
So this deed tells us there were other sons, but I don't know who they were.What is the first date that you find your Benjamin Forman in Ohio?And how do you know that he was born in Hampshire Co.?Was your Benjamin Forman possibly in Kentucky before he went to Ohio?
