And apparently Johnny Cash was born J. R. Cash.
From Wikipedia:
His mother wanted to name him John and his father preferred to name him Ray, so J. R. ended up being the only compromise they could agree on. When Cash enlisted in the Air Force, he was not permitted to use initials as a first name, so he changed it to John R. Cash. In 1955, when signing with Sun Records, he started using the name Johnny Cash.

He thought assuming that leading J made him seem more posh and WASPy

Edit: Funny observation - when you use the system that's linked to try and look up the public records, it won't even let you search for names with less than two letters.
That's exactly some of the cases we had to deal with some legacy invoicing systems (of which Kevin was not responsible, but I was ;))
I work in a small French town where Chinese people were quite rare until a few years ago. Their passports have a translation of their names in Latin alphabet, same for Russians.
However one day one of my user told me "hey I can't find some customers in your app, but I'm 100% sure I recorded them previously. Funnily they're all Chinese".
It turns out that to avoid querying the database too much I was starting to look for customers name once the user had entered at least 3 chars. Most of the Chinese names were only 2 chars like "Xi", "Wu" etc.
I clearly remember thinking at the time of writing the original code that nobody had only a 2 letter name :)
