A difficult one, Pete. You can specify the exact word
Rowe, but it still churns out Colmore Row and Easy Row, both of which had suppliers of ARP-related gear from mattresses downwards. Asking it to exclude
"Row " with the space, produces nothing. And there are hundreds of companies trying to recruit ARP people, such as factories and cinemas, so you get all that dross as well. Searching on the phrase
ARP Warden produces nothing either. As Chris says above, the naming of individual wardens is as rare as hen's teeth.
But (and there's always a but), if his wife's name was Florence and they lived at 188 Clifford Street, then here they are on the 1939 Register. He is shown as an assistant in a grocers, but if you look in the right hand margin, you will see that William is named as a Head ARP Warden and Florence as an ARP Warden. Frankly, I think this is as much as Rebecca is likely to find as the papers at the time did not tend to name rescuers for security purposes, as Chris has said. I've attached this as a file.
