> trying to remember which ones she's officially used
I had an uncle who was very proud of the fact that his birth certificate, passport, and the spelling he actually used for his first name all disagreed.
Slightly related story but, I too, found out my documents were out of wack when I applied for financial aid in college. I originally had two middle names at birth but then it was switched to only (the first) one a year or two later. My birth certificate had both names, my drivers license the first middle name, and my social security had the second middle name. It was a huge pain to get fixed, ended up just changing the two easiest to change to match the third.
