Seaton Family History

English: habitational name from any of various places called Seaton such as those in Cumberland, Devon, Durham, Leicestershire, Northumberland, Rutland, East Yorkshire, and North Yorkshire, most of which derive from Old English sǣ ‘sea, lake’ + tūn ‘farmstead, estate’, though the Leicestershire placename probably arises from an Old English personal name Sǣga or a stream-name Sǣge (from Old English sǣge ‘slow moving’; compare Seabrook) + Old English tūn.

Scottish: habitational name from Seton (East Lothian) from Old English sǣ ‘sea’ + tūn ‘farmstead, estate’.
