I saw the e-mail Southern California Genealogical Society (SCGS) – http://www.scgsgenealogy.com/ sent back in January 2019 announcing the Jamboree as well as checking on their website on a regular basis over the last few months. I am no longer a member of SCGS, and have never attended any of the Jamborees. Maybe one day I will make it.
Here;s the information – Southern California Genealogical Society Jamboree 2019 May 30 – June 2, 2019: http://genealogyjamboree.com/ Early Bird pricing ends April 21, 2019 = http://genealogyjamboree.com/conference-pricing/. There is a discount for members and membership is only $40/year.
