I found these interesting areas on Trenton Society and News that covers quite a few years in the 1800 - 1900s and thought some would be able to find naturalization, businesses, some residences, marriages, deaths or news article references listings. http://www.trentonhistory.org/Exp/Chrono.htm http://oldmillhillsociety.org/research/naturalization/DeclarationOfIntent.htm There are a few other sites off of the oldmillhillsociety.org and also the trentonhistory.org, too. Enjoy! Doris
