I am researching John and William Voss, brothers who show up in Virginia in the late 1790's. I have reason to believe that their father was from DE, NY or somewhere north and that he moved to VA in the mid or late 1790's. John and William would have been born appx 1740-1750. I feel that the name was changed during the move south. Father may have not made the trip south, or may have died enroute.
Maybe this is some of your Vose's that have disappeared?
