LDS does not use the Federal microfilm numbers. They use their own numbers issued in order as they receive and catalog the films. Rome Township in Crawford County's 1870 census is on roll #552,830 (my people are in Rome). Since they tend to list the townships in alphabetical order, I'd have to guess that the first half of the alphabet is on roll #552,829. Jeremy Nichols [FINK, NICHOLS, STEARNS]
