My brother Pete found this the other day, on the morning of our grandmother's 100th birthday party. She is the widow of Ernie Norman, and we are pretty sure she had no idea he was in the Langton unit - his daughter (also present) didn't know, and we are confident our late father would also have said something had he known. Of the names on the Langton page (http://www.coleshillhouse.com/langton-matravers-auxiliary-unit-patrol-purbeck.php) "Emie" should be "Ernie" (looks much the same on a computer screen, but it's RN rather than M), and "Hayson" should probably be "Haysom" (well-known local name). Hedley Lander's sons lived very near our grandparents (just up the hill from where the bunker was), and Nelson Burt was possibly a cousin, certainly someone our grandfather knew before the war (it's the sort of area where most people are cousins of some sort). Ernie was a fireman in the AFS during the blitz, stationed at Carter Lane near St Paul's in 1939 during the worst of it, and returned to Langton in about 1940/41. He died in late 1964.
