Coleman, Samuel Edward

y grandfather was Samuel Edward Coleman & I have his last will & testament from when he was in the "Army of the US, stationed at Fort Dix, in the County of Burlington, New Jersey". It has his rank as M/Sgt, branch as Air Corps, has his ASN # & is dated 24 July 1942 @ Fort Dix New Jersey. Family history states that he was reported by telegram to my grandma as missing/dead. Turned out he was a POW & not dead. However, when he returned my grandma, thinking he was dead, had moved onto another man. I am trying to find out more about this but have hit dead ends all the way around.
