English: Anglicized form of an unidentified surname, possibly German Schweitzer or Dutch Swijs, rare patronymic from Wijs ‘wise’ (see Wise ). The surname Swasey is no longer found in Britain. Compare Swayze , Swazey , Sweazy , Sweezey , and Swezey .
History: The name was brought to North America by John Swasey, a Quaker who came from England to Salem, MA with two sons, John and Joseph, in or before 1640. Banished from Salem because of his religious beliefs, he moved first to Setauket, Long Island, NY, and subsequently to Southold, Long Island. His son Joseph, who remained in MA and inherited his estate at Salem, kept the surname form Swasey, while John, Jr, adopted the form Swayze.
