Kiedis was born in Grand Rapids, Michigan, to Margaret "Peggy" (Noble) and actor John Michael Kiedis, known professionally as Blackie Dammett. His paternal grandfather's family emigrated from Lithuania in the early 1900s; the remainder of his ancestry includes Irish, English, French and Dutch. In 1966, when he was three years old, his parents divorced and he was then raised by his mother in Grand Rapids. His mother later remarried and had two more children, Anthony's half sisters. Each summer, he would visit his father in Hollywood for two weeks, a time during which the two would bond. He idolized his father and recalled, "Those trips to California were the happiest, most carefree, the-world-is-a-beautiful-oyster times I'd ever experienced. " In 1974, when Kiedis was twelve years old, he moved to Hollywood to live with his father full-time.
