SW's mother was 29 when she got married and was working on her brother-in-laws farm alongside SWs father. Her first daughter was born 3 years later and SW, 5 years after that that. In TWS SW describes her, "This ninety-year-old, strong independent woman had proudly told the story of how she was the first woman in the village to wear trousers, of how the other villagers had reviled her for it." Then having 2 small daughters, the family moved to live at the farmhouse with her sister who was 13 years her senior and brother-in-law. I do wonder what Victorian values that SW is referring to, other than that they don't like her boyfriend.
Oh, and she wore a (now infamous) powder blue costume to her wedding and her bridesmaid wore a grey two piece costume, in 1954, very un-Victorian! Report from newspaper.
