I had a 1st cousin 3 times removed, Mary Ann (Polly) Austin that married William F. Spence Sr. and had the following children, Robert, Rebecca, Catherine, George, William, John and Charles. I have nothing on William Spence Sr, other that he and Mary, married in White Co. in 1850
As children of William F Spence and Mary Austin you have a John Spence. Could this be John C Spence born about 1860, married Miranda Greer in 1880 White Co. Younger brother Charles was born 1867, time frame for being born about 1860 would be about right. Norm
