Hi Mike I show Unity as the wife of Granville but nothing else except she was born in 1810 in TN. Alexander, brother of Granville, is my GGG grandfather. Sorry I couldn't be of any more help. Have you been to the cemetery in Evansville where Granville is buried? It's very pretty. I have a picture of his stone if you'd like a copy. I can scan it and email it to you.
