First found in Lincolnshire. The family's earliest known family member is Sir Ralf of Bracebridge, who was born in 975 in Bracebridge, Lincolnshire, England. The first known family member to bear the surname "Kingsbury" was Adam de Kingsbury, who was born c. 1240 in Kingsbury, Warwickshire.

Many English families tired of political and religious strife left Britain for the new colonies in North America. Although the trip itself offered no relief - conditions on the ships were extremely cramped, and many travelers arrived diseased, starving, and destitute - these immigrants believed the oppurtunities that awaited them were worth the risks. Once in the colonies, many of the families did indeed prosper and, in turn, made significant contributions to the culture and economies of the growing colonies. An inquiry into the early roots of North American families has revealed a number of immigrants bearing the name Kingsbury or a variant listed above: Henry Kingsberry settled in Virginia in 1729; Henry Kingsbury settled in Boston in 1630 with his wife Margaret and son Henry, he later moved to Salem.
