My guess on that is it comes from "Ewige Liebe" so "eternal love". But maybe not.
The other also are very strange but it has the feeling of making names out of words.
"Schutzelia" is something like "Protectia", same for "Frühtrüne" but here "früh" only means "early" but It should be the "Früh" from "Frühling" so it's "spring".
The only normal name/word is Leidenschaft which means "Passion"
