I'm descended from Thomas Culwell, born in North Carolina in 1809. He's a brother of William Culwell, born in North Carolina in 1810.
Thomas Culwell Sr., born in 1773, their father, wasn't born in Ireland.5Three of his son gave documented testimony in 1880 that he was born in North Carolina.
In 1880, an M. Mayo, a female, born in Texas, circa 1858, and identified as "a neice" of Thomas Colwell (sic), was ennumerated with him on the census. She identified her mother's birth place as Texas, and her father's as Missouri.
