Marguerite christened a San Leandro ferry boat (I believe this was in March 1923), launched in San Pedro. These people attended. But who are they?
(Both Dave and Frank Anderson believe that it's Marguerite in the center of the 4th row up, with collar and hat. Barbara Cox thinks that Minnie is the partially obscured woman (in hat) just to the right of Marguerite.)
