Modern coinage from the Scottish word glen ‘valley’ (Gaelic gleann), in some cases perhaps representing a transferred use of the surname derived from this word. In recent years it has been used far beyond Scotland as a given name. Among well-known bearers of the name is the U.S. country singer Glen Campbell (b. 1936). There has been some confusion with the Welsh name Glyn, which has the same meaning.
German: 1. nickname for someone with deformed or otherwise remarkable toes, from Middle High German zēhe, zehe ‘toe’, ‘claw’. The term also meant ‘tough’, and in some cases the surname may have arisen from this sense. 2. variant of Zech 1.
