My ggrandfather, Addison B. Stone, b.7-29-1844 in PA, married his 2nd wife, Fannie Roberson, b. 1861 in Norborne, Carroll Co. MO, on June 7, 1885 in Las Vegas, NM. They had 2 children: Addison Borden Stone, b.Feb, 1886, and Mary Logan Stone,b.1887, both born near San Diego, CA. I'm trying to find out what happened to these 2 children . Is anyone researching this line of Stones?
