He was the son of Sir William Henry Roger Palmer, Bt and the great-grandson of Sir Roger Palmer of Mayo, who was MP (1768–1783) for Portarlington in the Irish Parliament. His only sibling Ellen married Archie Peel, a nephew of the UK Prime minister. He was educated at Eton and joined the Army.

He served in the Crimea War with the 11th Hussars and took part in the Charge of the Light Brigade of 1854. He exchanged to the 2nd Life Guards in 1856 (until 1870) and was placed on the retired list in 1881. He was granted the colonelcy of the 20th Hussars from 1891 until his death in 1910.

During the Irish Famine, he was known to have evicted many tenants.

He was High Sheriff of Mayo in 1888. On his death, Kenure Park passed to Colonel Roderick Henry Fenwick-Palmer. Sir Roger had married Gertrude Millicent, daughter of the Rev.
