* Mary Arden (1537-1608): This Mary Arden was the mother of William Shakespeare. She was a farmer's daughter who married John Shakespeare, a successful glover and merchant. While she didn't have a paid job outside the home, she was responsible for managing the household, raising their children, and likely assisted in the family business.
