I think you missed my point. I know there is a column for race but if you look at most of the censuses for Avoyelles parish the census take did not enter anything in that column. I realize that Creole was not an official race and don't think it is even today. Its just a term given to mulatto, quadroon, octoroon (as you say). A census taker would only know mulatto if both the parents were present and would not have anyway to know about quadroon or octoroon unless he asked. Of course it is left up to the census taker to mark the race (either officially or not) because people themselves did not fill out the census, the census taker did. I'm not sure why it matters if they lived next door to one another as each family is indicated by a family or house number so it wouldn't be mixed up between families.
