HeritageQuest is a database that is nationwide in scope and includes family histories, genealogical serials, local histories, and primary sources in full image. Also included is the ability to search Federal Census page images, indexed by name (head of household only). With resources on towns and families from all 50 states as well as Canada and the British Isles, the database includes 7.5 million fully searchable pages in addition to the census images. Not all census years are fully indexed as yet.

HeritageQuest also contains PERSI, the genealogy periodical index, Revolutionary War Pension records, and much more.
