>>>Keep in mind that "immigrants" from other colonies and the British Isles were already subjects of the Crown and there was no need for them to be naturalized as new citizens.<<< ________________ Neat subject area. Some literature suggests that English "citizenship" during the period generally was reserved to those born in England or the colonies, or provided citizenship by the sovereign or Parliament, but I doubt that the "born in" route applied in anything like full measure to all people born in the colonies ... for instance, enslaved African Americans and native Americans. For a discussion of how English citizenship applied to Jews during the American colonial period, see Search Out the Land: The Jews and the Growth of Equality in British Colonial America, 1740-1867, by Sheldon J. Godfrey & Judith C. Godfrey (1995), preview available on-line at http://books.google.com/books?id=ajizw3pz8IIC. Godfrey describes how even English citizenship ended up being bifurcated into classes.

A Wikipedia entry, Jewish history in Colonial America, at http://en.wikipedia.org/wiki/Jewish_history_in_Colonial_America, provides more discussion concerning how one group of Americans became colonial American citizens. The New York Genealogical and Biographical Society has some holdings addressing naturalization in colonial Pennsylvania and other immigration and naturalization resources, shown in a "Selected Bibliography for Immigration and Naturalization Research," available at http://www.newyorkfamilyhistory.org/modules.php?name=sections&op=viewarticle&artid=7.
