re slave/landowner "marriage": you are saying that I am NOT going to find any record or official document of their union, because of the law in TN at that time .. thank you.
re your questions: Henry W. Compton had 2 families 1) mulatto and 2) white, both "wives" named Ann/Annie:
-1860 census - although only listed with his mother Susannah, he was obviously living as a husband to mulatto Ann (maiden name) and they already had children
-1860 census - his mother Susan Mullen Compton died in 1860 after that census, so he must have felt free to be listed with his mulatto family after her death, as seen in 1870.
-1870 census - listed with mulatto Ann and children Joshua, William, Dennie, Maria L, Mary
-1880 census - listed with causian wife Annie Ward Compton and daughter Susan
-1880 census - shows all the mulatto children living on their own or with family and no record of mulatto Ann, who suppose to have died previous to 1874 marriage to causian Ann Ward.
The family 1) mulatto hildren grown, married and children of their own in later census .. no more record of mulatto Ann, mother of all the children in 1870 census. Thank you for your "marriage" information .. sad.
