Baron de Robeck is a title of the head of the Irish Fock family which has its origins in Sweden. Jakob Constantin Fock, a Swedish landowner, had bought the Räbäck estate in the parish of Medelplana, Skaraborg County in the province of Västergötland, and after serving as the acting governor there three times, he was created a friherre in 1778 by King Gustav III. His son Johan Henrik, after fighting in the American War of Independence, moved to England and was naturalised as a British subject under the name "John Henry Fock, called Baron de Robeck", by an Act of the British Parliament in 1789.
