Costin Family History

This interesting name, with variant spellings Cost(a)in, Costen, Costin etc., has two distinct possible origins, the first and most likely being a derivative of the Medieval male given name Costen or Costin, itself coming from the latin Constantine, (familiarly Costantine), from "constans" meaning steadfast and faithful. The name was popular throughout Europe having been borne by the first Christian ruler of the Roman Empire, Constantine the Great (280-337), and was introduced into England by the Normans.
