Anthony Kiedis's paternal grandfather’s parents were Lithuanian. His other ancestry includes Dutch, French-Canadian, English, Irish, Scottish, German, and distant French Huguenot.
Anthony Kiedis was born on November 1, 1962, in Grand Rapids, Michigan, the United States, to Margaret "Peggy" (Noble) and actor John Michael Kiedis, known professionally as Blackie Dammett. Peggy and Jack married on July 2, 1960, following a whirlwind romance which saw them married within two months of meeting; within about the same time Jack was cheating on his new wife.
When Anthony was a child, his father was close friends with Bono and his then-wife, Cher, who often babysat Kiedis. His parents split when Kiedis was 3 years old.
Thereafter, he lived with his mother and visited his father. In December 1967, Kiedis and his mother returned to live permanently in Michigan after Peggy began dating Scott St. John who persuaded her to return from Los Angeles to her native state. Scott and Peggy married in 1968, however, this was to be another short-lived marriage for Peggy and Scott was no longer permanently on the scene by the time their daughter, Julie, was born on March 12, 1970.
Eventually, 11-year-old Kiedis convinced his mother to agree to let him live with his father in California. His father earned much of his money from dealing marijuana and other illegal substances. The father-son duo used to have drugs together.
