Katherine Fowler was the daughter of a London cloth merchant and was raised a Puritan. She studied at a women's boarding school; John Aubrey reports she "loved poetry at schoole and made verses there." In 1648 she married Colonel James Philips, a Welshman and member of Parliament. After the Restoration she became one of the better-known poet-playwrights of the age, much admired by Abraham Cowley. John Keats was also an admirer.
