The San Joaquin Genealogical Society (SJGS) serves those interested in genealogical research in San Joaquin County, which is located in the northern part of California's Central Valley. We also seek to provide genealogical training and resources for our members and local residents who are researching their roots in other parts of California, the United States, and worldwide. Our membership is open to all.
 
We hope you enjoy our new website, which "went live" in early 2017.1 We are continuing to make updates and improvements, so check back often for new information, and please bear with us as our site undergoes further construction/modification.

About San Joaquin County
 
San Joaquin County is one of California's original counties, created when California became a state in 1850. It's named for the 356-mile-long San Joaquin River, the longest river in California's Central Valley. The river passes through San Joaquin County and empties into the Sacramento-San Joaquin River Delta, the largest estuary on the west coast of the Americas (North, Central, and South).
 
For maps showing how the boundaries of San Joaquin County and other California counties changed through the decades, visit the California State Association of Counties.
 
Incorporated cities currently within San Joaquin County are Escalon, Lathrop, Lodi, Manteca, Ripon, Stockton (the county seat), and Tracy; unincorporated communities are Acampo, Clements, Collegeville, Farmington, French Camp, Linden, Lockeford, Morada, Mountain House, Terminous, Thornton, Victor, Waterloo, and Woodbridge.
 
Historic settlements and communities that no longer exist include Atlanta, Banta, Bellota, Burwood, Carnegie, Castoria, China Flat, Collierville, Cox's Ferry, Dent (now Escalon), Dogtown, Elliott, Fair Oaks, Five Corners, Henderson Village, Holt, Hope Landing, Liberty, Lincoln Village (now within Stockton), Middle River, Mokelumne City, Mormon, Peters, Poland, San Joaquin, New Jerusalem, Peters, Taison, Vernalis, and Youngstown.
