Major Rudolf Mons

Mr David Morgan suggested that Rudolf Mons might have been the unidenfied corpse found on Somerton Beach Adelaide in 1948 based upon facial matching software - Betaface search.

He was unable to find any ancestry data on Rudolf Mons and all sources of information originate from a Vienna newspaper when he was awarded his Knights Cross of the Iron Cross and then MIA which could have been written by Hermann Goering. The only place a Rudolf Monz could be located in newspapers was in Australia in the 1920s.

However, it seems clear that Mons was killed in battle.
