Helping someone locate military information on thier father as named in parents marriage and divorce certificates - Jack W. McGann, (name could be John) married New Years Day 1944 to female Marine stationed as MCAS Majave in Glendale, CA. Shipped out by time daughter born Sept 1944 and her mother had gone back home to east coast June 1944. Mother never talked abount marriage and divorce. Daughter has a picture of him from waist up in what appears to be a khaki work uniform shirt. Older cousin told her she thought he was born in CO and younger than mother who was born 1920, but not sure this is correct information. Another Marine couple witnessed marriage and dauhter has a picture of the Nelsons in full dress uniform. I think Verl Nelson might have served in same unit as McGann, patch looks like First Marine Divison and Verl has a parachute pin above breast pocket. There is a possility McGann was in another service. Searched Ancestry with my subscription and she has contacted various organizations and looked up several John/Jack McGanns who served and came home from the war and she has written letters to them with no luck. Thanks for any help.
