Surname or Lastname
Scottish
Scottish : Anglicized form of the Gaelic personal name Eachann (earlier Eachdonn, already confused with Norse Haakon), composed of the elements each ‘horse’ + donn ‘brown’.English : found in Yorkshire and Scotland, where it may derive directly from the medieval personal name. According to medieval legend, Britain derived its name from being founded by Brutus, a Trojan exile, and Hector was occasionally chosen as a personal name, as it was the name of the Trojan king’s eldest son. The classical Greek name, HektÅr, is probably an agent derivative of Greek ekhein ‘to hold back’, ‘hold in check’, hence ‘protector of the city’.German, French, and Dutch : from the personal name (see 2 above). In medieval Germany, this was a fairly popular personal name among the nobility, derived from classical literature. It is a comparatively rare surname in France.

English : patronymic from Mathew; a variant spelling of Matthews. In the U.S., this form has absorbed some European cognates such as German Matthäus.Among the earliest bearers of the name in North America was Samuel Mathews (c.1600–c.1657), who came to VA from London in about 1618. He established a plantation at the mouth of the Warwick River, which was at first called Mathews Manor; later its name was changed to Denbigh. He was one of the most powerful and influential men in the early affairs of the colony. He (or possibly his son, who bore the same name) was governor of the colony from 1657 until his death in 1660.
