On 3 August 1874, at the age of 48, he married Christina Anne Jessica Cavendish-Bentinck, daughter of George Augustus Frederick Cavendish-Bentinck and Prudentia-Penelope Leslie. His wife was 30 years younger than him and it was not a happy marriage. The couple eventually separated, with Sir Tatton disowning his wife's future debts.
Sykes died in May 1913 at age 87, and was succeeded in the baronetcy by his son Mark. He owned 34,000 acres (14,000 ha) of land in the East Riding of Yorkshire.[7]
