Corvus / Corvinus give off really morbif vibes to me, and I haven't a clue why. I must admit they would make interesting mns.
Edmond Corvus sounds very regal. Lucien Corvus sounds good too, but the name Lucien sounds a bit slimy to me. I like it fine for someone else.
I prefer the combos Nathaniel Pleasant (he sounds so humble and great) and Simon Veritas :) Handsome boys.
I think Corvus and Corvinus are much subtler than Crow, although the connection is still there. Both have cool sounds, I think it just depends what it's paired with to be honest.
