I'm also looking for parents/siblings of a John A. Black (my 2x gr grandfather)b. ca 1830. John A. Black married Rebecca Epperhart in Morgan Co., Ky in 1856.John is witness to marriage of James H. Black (a brother?) to Margret Sergeant in 1854.In 1850 John is in the household of William Sergeant Black and William's wife, Margaret Howard Black.Also in residence is Jane Adkins.Believe Jane Black who married Strailey Adkins in 1848 is this person.William Sergeant Black moved to Fountain Co., Indiana prior to 1865 and sold his father-in-law, Cornelius Howard 250 acres in Morgan Co. Ky for $25.I cannot find anything in Fountain Co., In.If this rings any bells I would be so happy to share information as I have searched for John for 2 years.
