You'd just be ahead of the curve.
A load of people in the 60+ age bracket have it, so obviously an abundance of people once thought it was pretty enough to be popular. Its time will come again.
I was given a deeply unfashionable name - from my parents' parents generation (so what this name is to us). Nobody at all had it when I was growing up and I've yet to meet another one - but now you can't move for babies and toddlers with my name, or one of its variations (Isobel).
If you call a baby Patricia now, by the time she gets to her 20s, it will be the height of chic.
