And some parents know their kids will become werewolves.

English is not such a great language for this, because the meanings of many names aren't that obvious, but if the language of Hogwarts had been Hebrew many of the wizarding-raised kids would have had names related to the element or mascot of their parents' preferred House. Plenty of water, light/fire and earth related names, as well as some lion and snake names. Air is a bit harder, maybe the Ravenclaw parents name their kids after birds, or for intelligence/smarts. Obviously whenever a girl named Shalhevet (flame) gets sorted to Slytherin or a boy named Yam (sea) gets sorted into Gryffindor there's a family crisis somewhere.
