I'm researching same line. I think? Bowman was born abt. 1740 and was either father or uncle. Matilda married Isham Harvill in 1781. She was born abt. 1762. Elizabeth married Abram Cook also in 1781 and was born abt. 1760. There seems to have been at least 2 possible 3 brothers that went to NC around that time and there are many listings for the surname Cass. Possibly with your info we could figure it out.
