Hello.I'm trying to find an ancestor Marie Thomas or Thomason as listed on the 1880 Marshall county Alabama census.She is listed as a 16 year old mulatoo living with her parents Arviel and Elizabeth Thomason and siblings plus a Dude Bartley(?).Marie marries William Shade summer of 1880.

That is where my paper trail ends and brickwall begins.My great
great grandfather laters marries another lady in Tennessee in 1892.Any
suggestions are appreciated.I have yet to find Marie's parents or
siblings anywhere except on the 1880 census.

thanks,
Robert
