My nan was born in 1945, her mother was a nurse in London and her father also worked in the hospital. We know next to nothing about him - we believe his name was William Wilson and he served in WWI. He apparently had a wife and 2 sons ages 10 and 12 that were evacuated to Wales. In WWII he was supposedly too old to fight, so helped out in the hospitals in London in some way. All we have of him is the attached photo. He is the third standing from the left. Apologies if this is not a WWII photo, I'm not certain! Is anyone able to help identify anything at all from this image that might help in finding more information about him? Anything at all would be greatly appreciated! Many thanks.
Welcome to the forum. The photo looks like to me possibly air raid wardens or a sort of Home Guards ? I'm sure someone here will be of more help. You can also post the picture on our sister site WW2Talk.com . 2Talk is centrally British and European ww2 so that may help.
He would be part of what was known in London, and other large cities, as Air Raid Precautions (ARP) volunteers. The SP on the helmet is for "Stretcher Party." ARP were civilian volunteers helping in various ways with the aftermath of air raids. Some directed civilians to shelters, handed out food and drink during raids, assisted firefighters and rescue parties, etc. They saw service from the 1940 blitz through very late in the war including the V-1 and 2 attacks.
