The sons of Patrick...

The origin of the surname Paterson, in all its rich variety of spellings, stretches back through the mist of time to no less a figure than St. Patrick, the patron saint of Ireland.

In common with many names, the forename, or Christian name, of Patrick gradually evolved into a surname, taking forms that include Paterson ('son of Patrick'), Patterson, Patrickson, Patersoun, Patrison, Peterson and Patison.

Paterson (with a single 't') is the most common form of the name found in Scotland, with Patterson (with two 't's) predominating in the north of England.
