San Joaquin Genealogical Society
The San Joaquin Genealogical Society Welcomes You!

SJGS serves those interested in genealogical research in the central California area of the United States encompassing San Joaquin County, including the current cities of Escalon, Lathrop, Lodi, Manteca, Ripon, Stockton and Tracy, as well as areas of Acampo, Clements, Farmington, Linden, Lockeford and historic settlements no longer on the map. We also seek to provide genealogical training and resources for our members in the local area who are researching their roots in other parts of California, the U.S. and worldwide.  

San Joaquin Genealogical Society
 Established 1952
On 10 January 1952, Mary Curtis, with the help of Naomi Carey, planned an organizational meeting to form a genealogy society in Stockton, California. There were twenty four charter members. Sue Denuit served as our society's first president. From 1952 to 1956, all meetings were held in the homes of members. In early 1956, Reginald R. Stuart, Director of the California History Foundation at College of the Pacific (now University of the Pacific), offered the society space for membership meetings in the California Western Americana Room on campus. Three shelves were cleared in the room for our genealogy reference books. Many of the original books were donated or loaned to the society by members. In 1963, SJGS moved its genealogical book collection to the Stockton-San Joaquin Public Library, Cesar Chavez Central Library, where it remains today.*
