I can sort of see people not immediately remembering how many Rs or Ls to put in "Spurrill," even after they've seen it in writing. But "Esther?" That's a completely ordinary name with a very common spelling.

In any case, glance at the spelling, folks, when you need to correspond. Or if you not seen the name in writing? Well, asking about the spelling is both polite and kind. No shame in not knowing at first.
