This section features local research facilities in Contra Costa County where you can find information about your San Francisco East Bay Area ancestors. Lisa Gorrell, CG, CCCGS member and genealogy specialist, provides a first-hand accounting of the best resources for each facility.
 
Even if you do not have ancestors who lived in the area, you can learn about the type of life they might have led by studying history, agriculture, social customs and much more. Plus, the same types of records might be in an archive or museum in the town or county where your ancestor lived. We offer a downloadable PDF for some facilities profiled.
