I usually don't link to my own column on this board, but this was one where I was so shocked by my own findings that I thought it was worth posting it here.
I certainly knew
Aidan was rare until recently, but just how rare it was amazed me. Since it does have a historical origin, I assumed there would always have been a few out there since St.
Aidan's time. It amazed me that there was not a single
Aidan in the entire US census of 1880. So this name went from nonexistent to #1 status in 125 years. I think that's rather incredible.
