I wasn't surprised to find that my aunts who married in 1940 had their maiden name lightly crossed out and their married name written in the column, but what did surprise me was to find my cousin, who must just have been visiting my maternal gran and my parents on the day of the registration and was at school at the time, had her maiden name changed too. She didn't marry until 26 March 1955 and her record was altered on 6.9.1956 - the date is by the side of her married name. As her first child was not born until 23 June 1957, I wonder why someone decided to show her married name, long before she would have gone to the GP about her pregnancy.
