Thanks for the speedy response. There were 5 siblings. John Christmas Smith, a bachelor, he was admitted in 1955 and died a few months later. Then Florence May Smith, spinster, who was admitted 1951. Gladys, spinster, went in a day after her brother in 1955 age 57. I was told they were there, poor Florence was in Parc hospital which was the worse. I assumed the two girls had died in the 50's so was very shocked and upset to find Florence died in 1984 and Gladys in 1992. My grandmother was sibling number 4 and sibling 5 Winifred Mary died at 11 months. So my grandmother would have been the heir to Gladys estate.... which would amount really to zilch but was put on the Bona Vacantia list. She always claimed she was adopted, that she had changed her name by Deed Poll and sadly told as many people as possible that she was an illegitimate child of Royalty. I have now found out they were living in terrible conditions in a cottage. Her name was Gladys Smith on birth cert, 1939 census and death cert. She even survived the outbreak of Smallpox on her ward in 1962 which killed 14 inmates!
