I have succeeded in creating a census template for the years 1940 thru 2000 however I had trouble with the year 1930. It says the GEDCOM tag of "CE 1930" is already in use. For now I made it GEDCOM tag of "CE 1931" and was able to create the 1930 census template.
I would delete it but I can't find it. It does not show in the events templates.
