I wonder if Carrel Schwantz might actually be Karel. That's my first thought when I see カーレル
("Karel /ˈkɑːrəl/ is a masculine given name in Czech, Danish, Dutch, Finnish, Icelandic, Norwegian, Slovene and Swedish form of Charles, meaning Free Man.")
In German you'd take out the "e" so it'd be Karl but that would be カール in katakana.
