I certainly remember some .......111AAAAPlumbers in the London Yellow Pages as a lad.
There were stories of people changing their name in Australia (Aaron Aaronson) to get elected on a donkey vote, so the order of names was randomized.
I don't know if these stories are true.
My kids have a hyphenated last name; my wife's last name starts with A, mine starts with L, and the kids' last name is A-L to give them "alphabetical privilege". Also, she carried the kids.
