Commander Shelley Leopold Laurence Scarlett, 5th Baron Abinger (1 April 1872 – 23 May 1917)
Scarlett was the son of Lieutenant-Colonel Leopold James Yorke Campbell Scarlett, and a great-grandson of the 1st Baron Abinger. His mother had been adopted by Percy Florence Shelley, son of Mary and Percy Bysshe Shelley.
He succeeded his second cousin in 1903. In 1904, a Royal Warrant of Precedence was issued, which allowed Scarlett's siblings (Robert, Hugh, Ruth, Percy, and Leopold) to be styled The Honourable. Scarlett was a Commander in the Royal Naval Volunteer Reserve. He served in World War I from 1915-1916 in the Bedfordshire Regiment. He was serving at the Admiralty at the time of his death in May 1917 aged 46. He was buried at Brookwood Cemetery.
Though married to Lilia Lucy Catherine Mary White (daughter of the Right Honourable Sir William Arthur White) in 1899, they had no male heirs. Thus, Lord Abinger was succeeded by his brother Robert at his death.
