Damer was the son of Colonel George Lionel Dawson Damer, MP for Portarlington, 1835-47, and Dorchester, 1847-52, and the grandson of John Dawson, 1st earl of Portarlington.
Nicknamed ‘Hippy’, Damer was described as genial and ‘blessed with an appreciation of the good things of this life’.
Portarlington died of pneumonia while convalescing at Portland Lodge, his Bournemouth residence, in December 1892, and was buried in the churchyard of Came, the Dorset home of his family.
