I exchanged emails this week with a reader who has an unusually spelled first name. It's not complicated or impossible to pronounce, et cetera. It's just a seldom seen variation on a common name.
I asked her how often people misspelled it. She said that's pretty common and added that her mother-in-law has been misspelling her name for 20 years.
I didn't press her for details on that particular relationship. But I have a couple of guesses.
