I do think there is a connection, but need to do some more in-depth research. My line has an Elias (b. 1771). Nelms moved to Franklin Co. from Isle of Wight, VA. He was married twice. My descendant, James Norfleet Nelms is from second marriage, to Matilda (?). James Norfleet had a daughter Nancy (b. 1853) so she cannot be your Nancy, but is probably related - a niece or cousin (?). My direct e-mail is
