I am tracing the African American Gourdine line from Jessie Gourdine Gadsden to her mother Josephine Gourdine and her father William Gourdine(1837). WIlliam's death certificate indicates that his parents are Robert Gourdine (1812) and Dafney Gourdine. William is listed as Negro. The remainder of the family line is listed as white, going back to the 1600's. I know that many mulattoes passed for white, and that many plantation owners often had children with their slaves. But I am concerned that I may be tracing the wrong line. I am wondering if you have any information on this family and if there are any known separate lines African American and White?
