I've accumulated reasonably complete information on all the children of this couple - when born, died, married, buried, and names of spouses and children. Most recently visited the place of death of Rosa Matilda Isom (whose husband was not named Jacob Edwards, but William Edwards). I have a copy of her obituary(a photograph taken from a book of newspaper obits).
I'd be glad to share all this with anyone interested. One of their younger sons, Aaron Flem Isom, was my great-grandfather.
