This interesting surname is a patronymic from the English name "Amery", itself deriving from a Germanic personal name composed of the elements "amal", bravery, vigour, and "ric", power, introduced into England by the Normans. The first recording of "Amery" as a surname dates from circa 1182, when a Roger Hemeri was listed in the Cartulary of St. Mary, Clerkenwell (Essex). Thus, "Emerson", i.e., "the son of Amery or Emery", is first formed as a surname in records in the early 14th Century. William Emerson is mentioned in 1411, in the Charter of the Priory of Finchale. A Cuthbert Emerson is listed in the Register of the Freemen of the city of York, in 1498. The surname is recorded as Emerson, Emberson and Emmerson in the modern idiom. Ellis Emerson and Ann his wife with his son Thomas, aged eleven years, were inhabitants of Virginia, America having come in the "George" in 1623. A Mathew Emerson is recorded as being a member of Major John Farmers', troop of horse, in the Barbadoes on January 5th 1679. The first recorded spelling of the family name is shown to be that of Richard Emryson, which was dated circa 1300, Yorkshire Records, during the reign of King Edward 1, "The Hammer of the Scots", 1272 - 1307. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax.
