The James Madison University Library Subject Guide on Genealogy is a great list of websites and repositories that should interest all genealogists. In addition to links for all types of record group categories, there are also religious records links for the Anabaptist, Amish and Mennonite churches. If you continue to scroll down you will see links for websites for other religious records as well under the heading Church and Religious Records. Those with Virginia ancestors will be interested in the links found at the very end of the Guide.
Other Subject Guides can be found on the Subject Guides homepage.
