Carol, Yes there is a census for Dallas County in 1900, 1910, and 1920 availabe to the public. Most of the 1890 census was destroyed in a fire. I don't believe any of Dallas County 1890 survived. The 1930 census will be made availabe after 2002. Almost any large genealogical library should have these on micro-film or can get them on inter-labrary loan. James R. Rasco
