Leendert, good find. I just checked on the casualty lists for Montgomery County and he is listed as DNB.

There may be something in the squadron records for September, 1944 which could be ordered from AFHRA.

The "Le Valon" mentioned on the link above is probably "La Vallon" https://en.wikipedia.org/wiki/La_Vallon_Airfield
