Debbie, I know it's been a long time since your posting, but here goes. Your Francis Marion Harrison, b 1834 TN, was a brother to my Nancy Amanda Caroline Harrison, b 1828 TN, who m John Waller Street. They named a son James BIGGS Street. I know that Nancy and Francis's mother was Elizabeth ?, but have not found their father or what the connection to the Biggs family is. Do you know? I have info on all the siblings. Any help would be appreciated.
