In trying to research my Marshall line I'm trying to figure out which John Marshall is my ancestor from among the ones in the 1810-1830 U.S. censuses.

There are a few that are still being researched:

1) John Marshall in Calais in 1810

2) John Marshall in Lubec in 1820 and 1830 (I'm assuming these are both the same man, but could be two men)

3) John Marshall in East Machias in 1830

If anybody has information that can help me narrow down the possibilities, please let me know... information on birth, death, wives' names or children's names could help.

Thanks very much!
