(20 October 1949 - 1993) (his death) (6 children)
Phyllis' husband, attorney John Fred Schlafly, Jr., came from a well-to-do St. Louis family. His grandfather, August, immigrated in 1854 from Switzerland. In 1876, his older brother married Catharine Hubert, the daughter of a local businessman. Shortly thereafter, the three brothers founded the firm of Schlafly Bros., which dealt in groceries, Queensware (dishes made by Wedgwood), hardware, and agricultural implements. They later sold that business and concentrated on banking and other businesses that made them wealthy.
On October 20, 1949, Phyllis married lawyer John Fred Schlafly, Jr. and remained married until he died in 1993. They moved to Alton, Illinois, and had six children: John, Bruce, Roger, Liza, Andrew and Anne. In 1992, their eldest son, John, was outed as gay by Queer Week magazine. Schlafly acknowledged that John is gay, but stated that he embraces his mother's views. Their son Andrew founded Conservapedia, a conservative open-source encyclopedia, after voicing concerns that Wikipedia had a liberal bias. She is the aunt-in-law of St. Louis brewery owner Thomas Schlafly. She is also the aunt of conservative anti-feminist author Suzanne Venker, together with whom she wrote The Flipside of Feminism: What Conservative Women Know – and Men Can't Say.
