A search of the
German War Graves database does not show anybody by that name dead in June 1944. For all of 1944 there are only four Kenters recorded and none of them is a Hermann.
From a quick look,
the recent French history of KG 100 does not include any Kenter among the known personnel of the unit. The same book shows only one aircraft lost between 14 and 23 June; this was on the 17th, and again no Kenter in the crew.
