Hello, I wrote to a historical soc that has all censuses for all states. I was told that most 1870 censuses in NY are not indexed. I also requested indexes from the 1900 NY census and was told that this census is indexed only by the Soundex system, on microfilm, that there isn't a published index for most states for 1900. Does anyone know anywhere, if any, I can access the index for 1900 and how indexing by soundex works. Thank you very much. Marilyn reynolds@3-cities.com
