Despite being a middle-class white guy from the US, I've experienced three of these on the same day. When I met my future wife, my last name ("Coon") happened to be a (somewhat rare) slur on her ethnic background. At that time, a man couldn't automatically change names on his wedding day in California, so we had to go to court ahead of time to fill out a legal name change form. The paper form had only one blank for the entire new name. A Hispanic family ahead of us in line had a son whose last name was supposed to be [father's surname] [mother's surname], but his birth certificate had accidentally recorded his father's surname in the middle-name field instead. So the family wanted to move his "middle" name to the front of his surname. With only one blank for the whole name, the kid's current legal name had the same exact sequence of characters as the new legal name, and there was no place on the form to make a note. The judge asked if they were OK with adding a hyphen, and they were. Epilogue: each of my daughters has two middle names.
