I'm a desendant of John and Fanny through their son Jasper Canada Browning. Solomon Browning is indeed John's father - the 1880 Census you refer to shows him living with his daughter (John's sister) Margaret Fulton Browning Latta. Solomon's wife was name Gail Ellis. It is believed, although not definitely proven that Solomon's parents were Benjamin and Margaret Radford Browning. I have a little more info, but not much. Please contact me if you want more.
