A much rarer alternative to Alexander that also gives you the oh-so-cool nickname Nico. Nicander derives from the Greek name Nikandros "man of victory", which belonged to a 2nd century BC poet and grammarian.

Excellent candidate for use as an undiscovered surname name. Niven is the Anglicized spelling of the Irish name Naomhan, a diminutive of the word naomh which means saint.

If you're looking for a Nicholas substitute or namesake, Nicholson would make a more distinctive path to the likable nickname Nick, fitting in with other newer patronymics like Anderson and Harrison.
