Would this be available online, or is this normally available at a library? I now live in Colorado and hope that I could access this locally. At http://www.nara.gov/publications/microfilm/census/1900/1900pt6.txt, I found: WISCONSIN T1079 - 82. J-525 Peter--J-656 It looks as if the microfilm is not organized strictly by last name?? Thank you for the assistance! >Since you state that their last name is Peterson and you know the county in >Wisconsin that they live in, have you tried to locate them in the 1900 >Federal Census? If you're able to find them in there, you can normally get >their birth month and year, number of years married and when they came to >America. I've had great success in gathering info that way. Good luck
