Eldred Gregory Peck was born on April 5, 1916, in La Jolla, California, to Bernice Mae "Bunny" (née Ayres; 1894–1992), and Gregory Pearl Peck (1886–1962), a Rochester, New York–born chemist and pharmacist. His father was of English (paternal) and Irish (maternal) heritage, and his mother was of English and Scots ancestry. She converted to her husband's religion, Catholicism, and Peck was raised as a Catholic. Through his Irish-born paternal grandmother Catherine Ashe (1864–1926), Peck was related to Thomas Ashe (1885–1917), who participated in the Easter Rising less than three weeks after Peck's birth and died while being force-fed during a hunger strike in 1917.
