Weir remained single throughout his years with the Grateful Dead, although he lived for several years (1969–1975) with Frankie Hart. Hart had been a go-go dancer at the Peppermint Lounge in New York, had worked in Apple Records American marketing department, and had performed on the TV shows Hullabaloo and Shindig!. She was allegedly the inspiration for the Robert Hunter, Bob Weir song "Sugar Magnolia". Weir made her acquaintance through Mickey Hart, who dated her briefly. He met her following her first Grateful Dead show in New York in 1968. Her real name at that time was Frankie Azzara (from a previous marriage), but used the stage name "Frankie Hart" (after apparently "borrowing" Hart's last name). Although she and Weir never married, she adopted his last name after moving in with him and was subsequently known as Frankie Weir. On July 15, 1999, Weir married Natascha Münter. They have two daughters, Monet Weir (born December 19, 1997) and Chloe Kaelia Weir. Natascha's younger sister Leilani Münter is a race car driver in the ARCA Racing Series circuit.
