Dillon's family was involved in Irish revolutionary politics; her uncle Joseph Mary Plunkett was a signatory of the 1916 Proclamation and was executed after the Easter Rising.
His last marriage (1974-1989) was to the Irish novelist and children's writer Eilís Dillon, who edited his posthumous book, Modern Irish Literature: Sources and Founders (Oxford, 1994).
