Heather Louise McCartney is an American potter and artist who is the daughter of Linda Eastman McCartney and adopted daughter of Paul McCartney.
McCartney was born in Tucson, Arizona to Linda Eastman and Joseph Melville See Jr. , an American geologist. Her parents separated after eighteen months of marriage, with her mother marrying Paul McCartney in 1969 when Heather was six years old. During this time Heather was formally adopted by McCartney, also making an appearance in the Beatles film Let It Be. A halfsister, Mary, was born in 1969, followed by another halfsister, Stella, in 1971 and a halfbrother, James, in 1977.
