Brenda, If you are interested in his service records the only place you can obtain that information is from the National Archives of which the military services personnel records are a part.If service records are what you want, visit the NARA site at http://www.archives.gov/http://www.archives.gov/ .If you can't prove "next of kin" you will not be able to obtain the records.
If you just want to know where he is buried it is at the Fort Sam Houston National Cemetery, 1520 Harry Wurzbach Road, San Antonio, TX 78209 tel. (210) 820-3891 .It appears Gladys is buried in the adjoining grave but the surname is misspelled.Here is what the records indicate:
Outtereide, Gladys , b. 12/30/1902, d. 05/01/1963, Plot: I 178, bur. 05/03/1963, * Outterside, Clarence Edward, d. 11/17/1945, CBM USNR, Plot: I 177, bur. 11/21/1945, *
Otherwise if you are looking for descendants, Joan's suggestions are the way to go. Hugh
