It's funny, when I had my daughter, I wanted a name that would not be weird, but I also didn't want 5 girls raising their hands when the teacher called her name. I named her Nancy (after my Aunt Nancy). It turned out there were 2 or 3 other Nancys at her school, and one of them was in her class. It was never a problem, and Nancy kind of liked knowing a couple other Nancys. I really don't think she has met many Nancys since then.
I mentioned my Aunt Nancy. It was always funny when we visited Aunt Nancy and Uncle Herb. Nancy would be doing something or I'd have to call her, so I'd say, "Nancy!" My aunt (who I called Aunt Nancy, never just by her name) would always look surprised and say, "What? What?" lol
