Inspired by Mississippi-based journalist Sarah Fowler’s brilliant Washington Post story on the folks who changed their baby’s first name — 30,000 in the past five years alone — we asked the Social Security Administration for a list of the most-changed names. They ran the numbers back to 2017.

Apparently, it’s hard to spell after you or your partner have just gone through labor: The two most-changed names are “Issac” and “Chole,” and the two most-adopted names, as you might expect, are “Isaac” and “Chloe.”
