Etymology
Seabrook is a surname of English origin, derived from local place names. The name comes from a town by this name in Buckinghamshire, England, with origins further traced to a river name combined with Old English brōc meaning "stream" or "brook". A more detailed etymology from Wiktionary suggests the first element may be from the Old English personal name *Sǣga or the adjective sǣge meaning "slowly moving". Thus, Seabrook likely referred to a dweller by a slow-moving stream or one associated with the Saxon personal name.
