Check out: http://www.rootsweb.com/~njunion/census.htm Censuses, particularly ones from 1850 onwards, offer many clues such as names of everyone in household, age, and place of birth. Different censuses included more or less information. When looking at pre-1860 censuses, remember before 1857, Union county was part of Essex county. For federal censuses visit a National Archives branch or local library or check out the genealogy pages <A HREF="http://www.nara.gov/genealogy">www.nara.gov/genealogy</A> for ordering information. For state censuses contact the New Jersey State Archives, 185 W. State St., PO Box 307, Trenton, NJ 08625. ---Robin www.rootsweb.com/~njunion
