The earliest origination of the name at all is pre-Christian, being derived from Laurentum, the town in Italy famous for its laurel trees. For reasons unclear, Lawson is very much a north country surname. There are no less than seventeen coats of arms, all but one were granted to northern nameholders, and all seem to be associated with the Lawson family of Brough Hall, Yorkshire, whose origins are traceable back to the time of Richard 111, and 'The War of the Roses'.
