I think your John might be the brother of my Benjamin Manly.
My Mom, Jennie Manly (Richards) Burkett just died November 1 and I am in Atlanta staying with my adult children.
Please email me next week and I will try to give you a better sketch of my Manly family.
My Benjamin Manly was born about 1820 in Wayne County, North Carolina. He eventually came south and married Amanda (Champion) Brainard--she was married 1st to Cornelius Allen Brainard and had two children by him and then 5 children by Benjamin.
