I am a member of the Mercer family. My grandparents were Charles Mercer and Eva (Johnson)Mercer. She had 8 children as follows: Edwin, Grady, George, Virgil, Margie, Ruth, Vera, Betty..Mercer. They lived in Savannah, GA, Rayford, FL, and settled in Live Oak, FL. They settled in Live Oak somewhere in the 20's or 30's. There are still a lot of Mercer's in Live Oak and surrounding FL area's. I don't know if your family is part of my family. But if any of the info I've provided corresponds with your, please let me know.
