He is buried in the Parish of the Ascension Burial Ground in Cambridge, according to A Guide to Churchill College, Cambridge: text by Dr. Mark Goldie, pages 62 and 63 (2009). His ex-wife Olwen Phillis Francis (Lady Brogan), OBE, archaeologist and authority on Roman Libya and mother of four children, is also buried in the same cemetery; she later became Olwen Hackett on her second marriage, when she married Charles Hackett.
He appears to have had a working relationship with political scientist AFK Organski; a copy of the latter's book 'World Politics' (New York: Alfred A. Knopf, 1958) in the Glasgow University Library contains the following hand written note on the first blank page:
"To D.W. Brogan, In thanks for some delightful hours of talk, Kenneth Organski, New York, Aug 11 1959". The book was presented to the GUL by Sir Denis Brogan.
