In 1440 the name was written Glares, Glarer, Glaren, in 1500 Glor, and later, depending on the village where the family lived first: Glar, then Glaar and finally Gloor (Birrwil/Schwaderhof/Seengen).
The tithes, originally collected by Säckingen Abbey, later went to the Lords of Hallwyl who then gave them as a gift to the church of Seengen.
