I love
Autumn. I think it's a beautiful name.
I don't see why it would be silly to have the name during any other season; there are girls named
June,
May,
April, etc. and their names don't sound silly at any other time of the year. Ditto
Summer and
Winter.
I think it ages well, and I don't think it will become *too* popular. I can't see it breaking the top ten, because on the whole, people seem indifferent to it (well, at least the people I've met seem indifferent). I knew one girl in high school named
Autumn, but I haven't met one since, and that includes little kids.
