Den returned to civilian life and on 17 March 1956 he married Doreen Mildred Eunice Jones from Holsworthy who he had met when she was on a trip to the beach at Bude. They initially lived with Den's family near Bude where their daughter, Denise, was born. Shortly afterwards they decided to move Australia where Den used his carpentry skills in house building. Den and Doreen's son, Dean, was born in Australia.
Doreen increasingly missed home and eventually, after three and half years in Australia, the family returned to Cornwall where they lived with Den's parents near Bude while Den looked for work.
