I have a Brown Ernest Ainsworth in my database.I do not have a birthdate or any information about wife or children but if this is the right one, his parents were William Edward Ainsworth,b. May 10, 1878,in Smith Co., MS, d. September 1, 1961 in Mt. Olive,MS., m. August 17, 1897 to Maggie Margaret Saulters, b. May 22, 1880, d. February 14, 1961 in Mt. Olive, MS.Siblings were: Edna, John Wiley, Alma Leon, Etta Tyrone, Minnie Aletha, Ethel Rachel, William Patrick, James Melton and M.C. Ainsworth. If this sounds like the one that you are looking for, I have his Ainsworth line back four generations.
