I am told that my gggrandfather Sylvester Dent married into the Calvert family. I realize this is probably not the thing to ask, but does anyone have any info on this? They lived in Joplin MO in the late 1890's and maybe earlier. Their daughter was named Anna Melvina and I believe a son Will. Anna was born in 1867 in Bates County Missouri. Any help at all will be greatly appreciated. Darla Barkley
