Civil Batten was a Hilburn and she is in the 1850 Columbus Co. Census two pages over from Hamilton Hilburn who I believe is her father.
p. 101,Hamilton Hilburn- 69,b. NC (1780ish); Nancy. In household= Joseph Batten- age 4. I saw a posting sometime back stating that Hamilton Hilburn deeded land for Civil & Joseph Batten in 1847. On p. 102 of same census is Civil's sister's family- Ambrose Bullard-62? & wife Celia, age 44. Civil's family is on page 103: Wm Batten – 30 & Civil- 28.
They are in 1860 Columbus, NC census p. 27 w/Joseph listed with them; 1870 Columbus- p. 16. Drusilla is a mystery to me too as she is listed as white, black and mulatto in different census records.
I hope this helps. Joy
