The Best Print & Online Resources

Each guide contains a curated list of relevant resources for that county. The list is not exhaustive, but has been carefully curated by the NYG&B's experts. Researchers can be sure that the most essential resources are listed, as well as many lesser-known but still important items. 

This section also contains an overview of available online resources. Large websites like Ancestry.com and FamilySearch, are always covered, but researchers may find the small lesser-known websites listed to be the most valuable.

Crucial Geographic Information

Local, county, and state boundaries have changed continually throughout history - many place names have changed as well.   

Having a geographic mindset is really important for genealogy research - whether you're encountering a place name that's no longer used, or trying to determine the jurisdiction of a historical record, the charts in these county guides will provide information that is hard-to-find reliably organized elsewhere.

County Map



Each county guide contains a contemporary map of the county. 

This includes bordering counties and states, as well as local municipalities and American Indian Reservations. 

The map also notes if a county was formed from another county (a parent county), or if other counties were formed from this one (a daughter county). 

Major land transactions are very relevant to the genealogical researcher and are also noted here.
