Ivan The Baptist

Ivan (Bulgarian, Russian, Serbian: Иван, Ukrainian: Iван) is a male given name of Slavic origin common among Bulgarians, Croats, Russians, Serbs, Slovenians, and Ukrainians, equivalent to English name John, the Gaelic name Ian, the French name Jean, the German name Johann, or the Serbian name Jovan. Since the 20th Century, it has also been used as a popular given name among Italian, Spanish, and Portuguese speaking peoples. The name ultimately derived from the Biblical Hebrew name יוחנן Yôḥānān, short for יהוחנן Yəhôḥānān, meaning "Yahweh is merciful".
