On July 18, 1970, Carpenter married Frances Carroll Braxton Morgan Gates (born 1941), at Fair Hall, in
Mendenhall, Pennsylvania. The bride is a granddaughter of Philip Francis du Pont of
Fairville, Pennsylvania, a lesser known member of the
Du Pont family but direct descendant of the company founder
Éleuthère Irénée du Pont. She was previously engaged to John David Gates, a Yale graduate of Greenwich, Connecticut. They had six children. His widow,
philanthropist Carroll M. Carpenter, established the Edmund N. and Carroll M. Carpenter Professorship in Psychiatry at
Harvard Medical School. ==References==
