Re: Where was Forrest Gardner Early 1942?
Unless you can claim a family connection for NARA Military records (www.archives.gov) and they weren't destroyed in the 73 fire, the only way is to talk to family members. Forrest's sister Joanna Lintecum (Joan Lintecum in mother's obit) looks to be 82 and living in Kansas City, Jackson Co. MO, if the public records database is current.
Also Mrs Ben Solida from mother's obiit appears to be Forrest's sister Clara. She is listed as surviving her son Dennis Solida who passsed this November. Search "Clara Solida".
