Theres no such thing as a corny Space Marine name unless you ACTIVELY attempt to make them corny (e.g. Brother John the Big Hairy Bastard etc).
Different Chapters base their Marine names on different language roots (SW- Scandinavian, BT- N.European, DA/UM- Latin or 'classical' etc).
Its entirely up to you how they're named, and to be honest those names you mentioned seem to be perfectly fine.
