This is a most interesting question... thank you for asking. Silverlining, I had no idea that women were obliged to leave the civil service when they married right up until the 60's, as I was horrified to learn that my maternal grandmother had to leave her job when she married. I too then became interested in Women's Rights. She left home as soon as she could, as the eldest child with alcoholic parents. She went into service at a "very lowly level," is what I was told.
My paternal grandmother raised her 4 sons, and waited on her husband hand and foot as far as I can work out. She grew fruit and vegetables in the large garden, and raised chickens... the eggs of which my grandfather would give away, with great largesse!!!! Perhaps it was the way of the world at that time, but when she died, early 1950's, my grandfather, who I loved dearly, married his housekeeper.
