This isn't my nomination, but I think I'm the only one who's written in the fandom. Jane Duncan is best known for the "My Friends" series, which is indeed semi-autobiographical. Its heroine, like the author, lived part of her childhood in the Scottish Highlands, works in a factory during the war, marries an engineer who emigrates to Jamaica, and returns a widow to become an author.

However, under the name Janet Sandison, Jane Duncan also wrote the "Jean Robertson" series . It is a completely different series and not semi-autobiographical.

The setting is a fictional commuter suburb of Glasgow. The first book is about the childhood of the main protagonist, "wee Jeanie", who comes from the slums. In later volumes, she's housekeeper for an upper middle-class family. However, the series interweaves the lives of various people from other parts of the town, all of whom are affected in one way or another by knowing her.
