Known as Dominick, he was a portrait painter like his father, Simon Elwes.
At the age of 26, Dominick met, and wished to marry, 19 year old shipping heiress Tessa Kennedy. Tessa’s parents objected to the union and in 1957 obtained a restraining order to prevent the couple from marrying.
Dominick and Tessa eloped to Havana, Cuba, where they wed in a civil ceremony in 1958. When revolution threatened the stability of Cuba the couple fled aboard a raft to Miami. They wed again in New York before returning to England.
Dominick turned himself into the authorities and spent two weeks in prison for contempt of court. The couple had three children, Cassian, Damian and Cary, before divorcing in 1969.
Dominick was a good friend of Lord Lucan. When Lucan disappeared in 1974, after the murder of his children’s nanny, Dominick gave information concerning his friend to the press. Other friends viewed this as a betrayal. He committed suicide in 1975.
