I had a paternal Cousin by the very distinctive name of Arnold Joseph Klosser, born (Boer ?) in South Africa C1919. He had 2 younger brothers Gerard and Kendall and their Mother was my Aunt, Natalie C. v Klosser (nee Newman). They all came back to the UK in 1929 [Ancestry passenger lists*] having long dropped the germanic 'van' from their name. * There is only Natalie,Gerard & Kendal on the passenger lists ?
Family story insist they were ALL together ???
Arnold was educated initially at Anfield Boys School and at the age of 11 (1930) is mentioned in the school diaries as having set an incredible speed at swimming 100yrds. He and brother Gerard gained quite a reputation for their swimming prowess and were awarded many trophies. Arnold trained under my Father and became a 'junior' electrical engineer eventually going to Lpool Collegiate and on to L'pool Uni to study Law but was dismissed as a consequence of breaking into the study of whoever kept the Law exam papers and trying to steal them.
I had to chuckle when I was told that little nugget !

He joined the Royal Corps of Signals and became a professional soldier being awarded the Military Cross in 1942 for a very daring covert mission. He married a Merseyside woman named Ivy Hall and so far I have not found any record of the event?. They had a daughter in 1939 who when grown,in about 1960 married had a son herself (I already know their identities).
Some time during the 1950's Arnold had the wanderlust and left Ivy and the family to return to Africa where he settled in Zanzibar and ran two boats between there and Dar es Salaam. I know all this to be fact from older family members (and there are more than one account) yet,apart from his war citation at the NA,and possible probate records with the South African Gvt(2001) HE doesn't appear to have had any UK existence on record that I can find ? His brother Gerard is also on file at the NA for his wartime exploits but its 'most secret' and 'a closed record' till 2025.
Perhaps ironic, but some members of family say Gerard settled down in Germany after meeting a German girl during the late 40's.
Ivy Klosser died in 1986 in Birkenhead.
Arnold J. died in Zanzibar 1970's.
[Gerard is believed settled in Germany and remains there.] Kendall stayed a confirmed bachelor and remained in N.Liverpool until after Natalies' death during the 1970's. He sold the house and was believed to have settled on the Isle of Man. Both long dead by now I suppose ?
Any suggestions as to what & where I might try next would be welcome,I have run out of ideas.

Couldn't get anywhere with the swimming & trophies leads either.
