Major Brian Dear Butler MC; 3 Commando

I'm researching Brian Dear Butler in order to create a biography to leave at his grave in Ranville War Cemetery. He was a member of 3 Commando East Surrey Regiment. Any information on him or his family members would be extremely helpful, I know his wife was Hannah Wilson Briggs, he had two children named David and Patricia, he had three brothers named Eric Alan and Hugh, and his parents were Joseph Butler and Ellen Sarah Dear. He attended Kings College School and Kings College London University, had a teaching diploma and was a master at Wilson's School. He grew up in New Malden Surrey.
