Early life
Portarlington was born on 19 August 1858. He was the eldest son of Lionel Dawson-Damer, 4th Earl of Portarlington and Hon. Harriet Lydia Montagu. His younger sister was Hon.

His father was the only son of the Hon.

His grandfather served as the Comptroller of the Household and was MP for Portarlington and Dorchester. His maternal grandparents were the former Magdalen Hurley (a daughter of Lt.-Col. Thomas Hurley) and Henry Robinson-Montagu, 6th Baron Rokeby, Major-General commanding the Brigade of Guards.

He was educated at Eton College.
