Looking for information on Smith Jenkins such as parents, siblings, etc.

He was born in 1802 and married Nancy Smith 20 March 1832 in Madison, Virginia.

His children were:

George Washington - b1834
Joel Booten - b1837
Eliza Ann -b1835 (my gg-grandmother)
Silas Bruce - b1845
William - b1847
Sarah Elizabeth - b1849
John Alfred - b1853

Any help on this would be greatly appreciated.
