Mary, The American Battle Monuments Commission takes care of all US military cemeteries overseas and their web site lists all who are buried in them from both World Wars. I tried every spellining I could think of, including HUMENIK, and only got one hit. That was for John Humenik who hailed from Virginia. Obviously not the guy. The only other possibilites are; he used a different spelling or a different surname or that his body was returned to the states and buried in a civilian cemetery.
