These are names from the full 1930 SSA list which are so obscure no one has ever guessed them on Sporcle quizzes from those years. (I did one like this earlier for a different year. Some letters are missing because there's no quiz for them.)
No spelling changes, even if it looks like a typo - it's not. :)
