Erikson married Canadian-born American dancer and artist Joan Erikson (née Sarah Lucretia Serson) in 1930 and they remained together until his death.[21]
The Eriksons had four children: Kai T. Erikson, Jon Erikson, Sue Erikson Bloland, and Neil Erikson. His eldest son, Kai T. Erikson, is an American sociologist. Their daughter, Sue, "an integrative psychotherapist and psychoanalyst",[62] described her father as plagued by "lifelong feelings of personal inadequacy".[63] He thought that by combining resources with his wife, he could "achieve the recognition" that might produce a feeling of adequacy.[64]
Erikson died on 12 May 1994 in Harwich, Massachusetts. He is buried in the First Congregational Church Cemetery in Harwich.[65]
