Looking through 'Fighter Command Losses' - Franks. I find that during the period 10 - 12 May 1940 the Command lost 13 aircrew, 12 can be accounted for, the only one given as having no known grave is S/L. J M. Wells, shot down attacking an airfield at Waalhaven, Holland in Blenheim II L6616 R/600 Squadron on 10th May.
Just looked at the CWGC web site and come up with the following for S/L. Wells.
