According to Source:Merrick, George Byron. Genealogy of the Merrick-Mirick-Myrick Family of Massachusetts, 1636-1902, p. 3, the name Merrick traces back to Meuric ap Llewellyn, Captain of the Guard at the Coronation of Henry VIII, in 1509. "From him the name 'Meyrick', signifying 'Guardian', is derived as a surname, in pursuance of an act of Henry VIII., requiring that the name of every man at the time should be borne by his descendants as a surname."
