Cobain was born at Grays Harbor Hospital in Aberdeen, Washington on February 20, 1967, the son of waitress Wendy Elizabeth (née Fradenburg; born 1948) and automotive mechanic Donald Leland Cobain (born 1946). His parents were married on July 31, 1965, in Coeur d'Alene, Idaho. His ancestry included Dutch, English, French, German, Irish, and Scottish. His Irish ancestors emigrated from Carrickmore, County Tyrone in 1875. Researchers found that they were shoemakers, originally named "Cobane", who came from Inishatieve, a townland within Carrickmore. They first settled in Cornwall, Ontario, Canada, and then in Washington. Cobain himself believed his family came from County Cork. His younger sister, Kimberly, was born on April 24, 1970.
