Apparently you need your parents' names to apply for a marriage license in Connecticut (or maybe just Groton?). My FMIL has been married several times, so I emailed her to ask for her legal name (since I wasn't sure what was legal and what was just social use). She apparently doesn't even know her own legal name anymore - she isn't sure if her middle name is FI's last name (her ex-husband's) or the middle name she was given at birth.
I'm getting a good old laugh out of this, because I don't assume they'll actually check up on it too far, and I'm going to use what she's used on her tax forms so the government has accepted it before... but wouldn't it be a funny story to tell our future children, "Daddy and Mommy's marriage was declared invalid because Grammy couldn't remember her own name"???!!!
What's the most unexpected and unusual issue you've come up against in wedding planning?
