Gwenwynwyn is Welsh in Origin.

Gwenwynwyn is a medieval Welsh masculine name, pronounced roughly gwen-WIN-win. It derives from Middle Welsh gwenwyn, “poison/venom” (from gwen/gwyn “white, blessed” used ironically in the compound), with a reduplicated -wyn that likely serves emphatic or stylistic effect - hence a traditional gloss like “venom upon venom.” Though stark in literal sense, such forceful compounds were not unusual in early Welsh naming, and the familiar elements Gwen/Gwyn remain widespread in modern names.

Usage is almost entirely historical. The best-known bearer is Gwenwynwyn ap Owain (d. 1216), ruler of southern Powys; his realm came to be called Powys Wenwynwyn after him, and his descendants later styled themselves de la Pole of Powys. Documented variants include Gwenwyn and the mutated form Wenwynwyn; medieval Latin and English chronicles show orthographic fluctuations. Today the full name is exceedingly rare, while related forms like Gwen, Gwyn, and Wyn are common.
