English and German: metonymic occupational name for a glazier or glass blower, from Old English glæs ‘glass’, Middle High German glas. In English, the name may also derive from a nickname from Old French glas, clas ‘clash of arms, noise, tumult (of battle)’.
Irish (Ulster), Welsh, Cornish, and Scottish: from an Anglicized form of the epithet glas ‘slate colored, gray’, or any of various Gaelic surnames derived from it.
German: from an altered form of the personal name Klass, a shortened form of Nikolaus (see Nicholas ). This surname is also found in France (Alsace and Lorraine).
