Scottish (Caithness) and English: from the Middle English and Older Scots personal name Swan, an Anglicized form of Old Norse Sveinn (from sveinn ‘lad’), + -son. In northern England, Middle English Swanson was in fact an occasional variant of Swainson . In some cases the name may also arise from Middle English swan(e), swon(e) ‘swineherd, peasant, male servant’ (Old English swān) + -son, but this is unlikely to be the usual origin. See Swan .
