I'm not a fan of
Mary (or
Marija,
Maria, etc.), they are very common and
Mary especially seems dated to me.
I love
Victoria (prefer
Viktoria), I've met 3 or 4 and they have all been in their 20s or younger and they all go by their full name (but then I live in Croatia and we're not 'nickname obsessed' and we consider it rude to call people by anything other than what they've introduced themselves as).
