I was watching "Hotel Transylvania" (kids' movie, kinda cute) where the daughter's name is Mavis. I never really liked the name but after hearing for 80-odd minutes it kind of grew on me. The kid's a teenager but you also see her as a toddler and whatnot.
WDYTO Mavis? I assume a lot of people will see it as an old lady name and I kind of agree.
