SIMPSON
As described in historical dictionaries
Patronymica Britannica (1860)
SIMPSON. 1. A Buckiniihamshire parish. 2. The son of Simon. The Simpsons of Knaresborough deduce their lineage from the time of Edward the Confessor, and from Archil, a Saxon thane, living in that reign, and in the reign of the Conqueror. Among his other )ossessions was the manor of Clint in Yorkshire, where his posterity resided in the XIII. and XIV. centuries, writing themselves De Clynt. The name of Simpson (or Simon's son) was adopted from Symou, son of William de Clynt, who was living in the year 1300. See B.L.G. However contrary to our modern notions of good taste, there are several other instances of families having disused a territorial surname in favour of a patronymical one.
