First found in Lincolnshire, where the name is associated with the parish of Moorby.

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 Moorby or a variant listed above: Stephen Morby, who settled in Maryland in 1669; Richard Moorby, who came to Virginia in 1724; Samuel Moorby, who was on record in the census of Ontario, Canada in 1871.
