And this site
https://en.wikipedia.org/wiki/List_o...n_(L%E2%80%93N) says:
Born Bromley, Kent 13 December 1920; Commissioned February 1940
KIA 15 April 1942 whilst serving with 234 Sqn, aged 22
There may be a typo, because, if he was 22 in April 1942, then December 1919 seems more likely than December 1920.
Do you happen to know which date is the right one?
