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.
Possibly an altered spelling of German Tippe, a metonymic occupational name for a tub maker, from Low German (also Rhineland) tibbe, tippe ‘wooden tub’, ‘vat’; or of Tibbe, from Tiebbo, a short form of a Germanic personal name formed with Old High German diot ‘people’ + brand ‘sword’ or berht ‘shining’.
