Of only indirect help but, according to those probate details, his brother was a Derek S Allhusen: there can't be many of those. Assuming it's the Derek I'm thinking of, he was made Major and won an 'American Silver Star Medal' for his actions in Italy with the 9th Queens Royal Lancers having transferred from 24th Lancers. Derek is mentioned several times in the 24th Lancers history 'None Had Lances'. I'll see if there is any reference to his brother. Edit: DBF just beat me to the reply!
Clive If you do a Google search for Derek Allhusen you will find lots of information including a rather impressive blog mentioning many members of the family. Sorry but time precludes more input from me at this stage. They were clearly a very wealthy family and Derek was a member of the British Olympic equestrian team. Must be lots more info out there that should help you. I looked in NHLances but there is no mention of the brother. Died on active service therefore should be shown in 15/19RH war diary as well as on the death certificate? Steve
