James Sorenson

James Sorenson

President

James Sorenson has been seriously pursuing genealogy since 1994 and it has led him to visit more than 30 courthouses and at least that number of libraries. In the past couple of years, he has become more interested in DNA as a means of finding cousins, filling knowledge gaps and discovering surprises. Jim still gets excited about tracing a family, even when it is not his own. He has been a CGS member since 2007, and since 2010 he has been an active volunteer on the research and investment committees. Jim has also co-­led CGS sponsored research trips to Salt Lake City and has previously served on the CGS Board.

Joanna Shear

Joanna Shear

Vice President

Joanna Shear was born in Boston, grew up in Missouri, and landed in the Bay Area 21 years ago. A member of CGS since 2016, she has a BS in physics from Indiana University, an MSE in industrial engineering from Georgia Tech, and has completed Boston University’s Certificate Program in Genealogical Research. She was first drawn to genealogy by an unknown name on a mysterious engraved silver chalice, which led to a reunion for family separated by the Holocaust. Eleven years down the road, she is deep into the history of her Jewish ancestors as they moved within Europe and emigrated to other continents. She now also uses DNA to go beyond the documentation and trace new family connections. As her research for family and others has grown into new areas, so has her dedication to making genealogy open and accessible to all.
