BACKGROUND
*************************
The surname WILLIAMSON is a common English and Scottish patronymic name meaning "son of William".
It derived most predominantly from the popular Germanic personal name "William" (meaning "resolute protector").
Because "Williamson" is a patronymic (meaning "son of William"), it emerged within different regions of the world throughout recorded history.
As a surname, it spread widely across Britain and Ireland, with early forms appearing in England and Scotland from the medieval period onward.
One prominent example can be observed within the Scottish Highlands, where families using various spellings of these names (i.e., William and Williamson) allied with major regional powers for protection - most notably Clan Gunn and Clan MacKay.
WILLIAMSON is also recognized as a common Americanized form of various Scandinavian and German surnames, including WILHELMSEN (Norwegian, Danish, and North German), WILLEMSEN (Dutch and North German), and WILHELMSSON (Swedish).
These foreign patronymic names were often adapted to the more common English spelling WILLIAMSON upon immigration to North America, particularly during the 19th and early 20th centuries.
