April always seems fake. OK as a stage name but unlikely in real life. And I've never met one. I know a few
Avril people though, and I much prefer it.
I don't really think of
May as a month name. It's a family name and I quite like it, but I prefer
Maeve or
Mabel. And where I live,
April and
May are autumn, not spring. Not sure if that makes a difference.
