In searching the 1939 Register I have discovered my relative at an address which says New Southgate,Harrow U.D., Middlesex on a page with only women listed, various ages. I suspect its a Hospital, as she died in 1943 at Friern Hospital, Frien Barnet, which I know was a Mental Hospital. Any idea how I can tell where she was in 1939, as you cant look at the previous page to find the address. She died of chronic nephritis, according to the death certificate, with the words Indefinite PM, certified by a Doctor. Can I assume she was there as a Mental patient? Any ideas?
