Polly Baker is the story of a woman put on trial in 1747 for having an illegitimate child. She had been convicted five times in the past for this same crime. Each time, she said, the full blame was placed on her shoulders but not the father's. The story ends as she is set free and marries one of the magistrates in charge of her trial.

This story was actually written by Benjamin Franklin as a protest to the unfairness of the early judicial system charging women for having illegitimate children while not charging the fathers. Franklin himself had an illegitimate son named William Franklin.
