Yaroslava
This name derives from the Slavic name “Jarosláv (Яросла́в)”, composed of two Old Church Slavonic elements: “jarŭ (*jarъ) yáriy (я́рий)” (furious, angry, eager, impetuous) plus “sláva (сла́ва)” (glory, fame, renown, honor, repute, reputation). In turn the name means “one who is famous and renowned for his fury”. Jarilo is Proto-Slavic deity of the sun, spring, and fertility. However, with the adoption of Christianity in the Slavic countries the name began to be commonly understood not as a reference to a pagan deity, but rather to the "fervent worship of God". Yaroslav I was thrice Grand Prince of Novgorod and Kiev, uniting the two principalities for a time under his rule.
