The only problem is I am not finding much because of the date of birth for your mom. Census in the state of Virginia only go bak until 1930. IF you had his father's date of birth and place, it would be a little bit easier. Is Rodney still living?
There is another person online by the name of Bill Furr. He has done extensive research on the Furr families. Maybe he could help where I can't. I am willing to if you can find other information. Don't give up... last year I hardly knew anything about my Furr family side... now I have them traced back as far as 1655 when they came over from England.
