Standing from left to right:  Gary Allen Mitchell, Gilda Aileen (Mitchell) Roberts, Glenda Mae (Mitchell) Gaw, Glendon Jeffrey Mitchell

Picture taken probably just before Brinkley Allen Mitchell was to go overseas for World War II.  He is the soldier sitting on the far right.
 I don't know who the other two men are.  The picture was taken at the Casablanca Restaurant in Washington, DC.
