John Regehrthis paper came up in my feed but it's not me who's an author 
Per Vognsen@regehr I had a friend back in middle school whose entire family (parents and all four kids) had first names starting with K and it was very much intentional. And none of the names were traditional Danish names, so they were really stretching, e.g. my friend's name was Kian.
Sam Tobin-Hochstadt@pervognsen @regehr we have friends where all of their names start with L
