Just found this thread so il” add mine
The Rent'o'kill operative that had attended to our first house prior to our moving in was a Mr Peter Grubb. He actually lived next door to my parents.
And when I was a striplling, I was in the AFC and within our area we had two detachment leaders who were brothers, Lieutenant Key, and 2nd Lieutenant Key. They were both in the same profession, and members of there trade organisation that of the Master Locksmiths Association. I bet you guessed that didn’t you.
