I have a copy of the volume 6, number 1 issue of William and Mary Quarterly dated 1926 that includes a genealogical query from Semple Davidson Roberts about various Sweeney, B(r)ooker, Dunnavant and Willis relatives of possible interest to you. Send me a message at sweetmolly2004@hotmail.com and I can send the file to you. Meanwhile, look for Martin Sweeney (1825-1871) and Martha Dunnavant Willis (1830-1903), parents of Vaiden Brooker Sweeney, born in New Kent, VA in 1857.
