Looking for information on Catherine (Kitsy)??/Goff/Huggins (b.1819 NC - d.1899 SC)?

Don't know maiden name, but she is confirmed mother of:

- Azariah Goff (b.1844 NC, Civil War Veteran
- Henry M. Goff (b. 1845 NC, Civil War Veteran)
- Alva G. Goff (b. 1852, NC)
- George B. Huggins (b. 1854, SC)

I believe she was at one time married to Henry M. Goff of Surry, NC. Maybe he died, because then she and boys came to SC; and boys lived with James and Sarah Williamson per the 1850 SC census(maybe relatives?).

Then Catherine had a son Alva (b.1952/3). Recent DNA indicates his father was of Australian or Arabian descent and not African-American as originally suspected.

Next, Catherine married William Huggins and had a son, George B. Huggins, Jr. (b1854 SC); however, Azariah and Henry B continued to live with James Williamson.

I have been researching this for a very-very long time and have hit a brick wall.

Any help you can provide would be welcome.
