KEITH ANDERSON

Transferred use of the Scottish surname. The principal family bearing this surname were hereditary Earls Marischal of Scotland from 1455 to 1715. This is one of a number of Scottish aristocratic surnames that have become well established since the 19th century as boys' names throughout the English-speaking world, not just in Scotland. Others include Bruce, Douglas, and Graham.

Scottish and northern English: very common patronymic from the personal name Ander(s), a northern Middle English form of Andrew. See also Andreas. The frequency of the surname in Scotland is attributable, at least in part, to the fact that St. Andrew is the patron saint of Scotland, so the personal name has long enjoyed great popularity there. Legend has it that the saint's relics were taken to Scotland in the 4th century by a certain St. Regulus. The surname was brought independently to North America by many different bearers and was particularly common among 18th-century Scotch-Irish settlers in PA and VA. In the United States, it has absorbed many cognate or likesounding names in other European languages, notably Swedish Andersson, Norwegian and Danish Andersen, but also Ukrainian Andreychyn, Hungarian Andrásfi, etc.
