Looking for more information on Benjamin S. Whetzel Sr such as wife's maiden name and his parents, and death date.

What we currently have is:
b. abt 1810 in Virginia
d. bef 8 Aug 1850
Married: Sarah "Sallie" (b. abt 1812)
Children (we have so far): Mahala Ann Whetzel (1845-?), Benjamin Franklin Whetzel Sr. (1848-1928), Satira Whetzel (1848-?), and Joseph S Whetzel (1853-?)

Any help would be fantastic! :) Thanks!
