My great Aunt Pearl l Mann was a school teacher at city school in Chattanooga Tenn. in 1930.I am trying to find out something about her or the school but i don,t know where to look.I called their Library and they said the board of education don't keep records that far back.I would love to see something with her picture in it.Where do i go from here. I have not seen anything about black school annuels on Ancestry.com. They seem to be all white. Anna
