The Beginning of CVGS?

Marg W. passed a clipping from the Sunday, October 23, 1983 edition of the Chula Vista (CA) Star-News to me the other day. It reads:

"A beginners class for those interested in tracing their family tree will be held from 10 a.m. to noon tomorrow at the Chula Vista Public Library, 365 F St. The class is offered by the Chula Vista Genealogy Section of the Chula Vista Historical Society. for more information, call 421-5371."

I note that we are coming up on the 25th anniversary of this "beginners class."

Is this class the beginning of the Chula Vista Genealogical Society? Evidently, there was a genealogy section to the Chula Vista Historical Society. I wonder if the CVHS has anything more on the genealogy section, and when CVGS was formed?
