1621-29: Plymouth [1]
1630: Massachusetts [7]; Virginia [1]
1631-39: Plymouth [6]; Massachusetts [26]; Rhode Island [2]; New Netherland [2]

I have a minimum of 8 families that I do not have a year or decade of arrival for. All eight fall into the pre-Revolutionary War era. Documentation on ancestors from these families begin before 1776; most before 1750.
