Comments (Meaning / History Only)
I don't think "jaro" means "spring"; an adjective "jary" means "fierce" in some Slavic languages, so Jarogniew should show a "great wrath" to his enemies, such as Casimir should "destroy their peace" (see CASIMIR). Names like this are an inheritance of a time when the Slavs were ferocious warriors.
