My fathers middle name was Homer, DH's middle name is Barton. So we joked that we were going to name DS 'Homer Barton' and call him Homely Bart for short... And no, our last name isn't Simpson.
My great-grandmothers name was Nellie. I have a great great Aunt named Olive and one name Ermel (yeah, like the cat from Garfield, but loooooong before then). My daughter's name is Arwen and people are forever spelling it phonetically, like Arwin or Arwynne, which drives me nuts!
My great aunt was named Zilla. we wanted family names, but that one? God! Zilla... just thought that would be awkward. my cousins middle name is Oe. My other cousin is named Fang... but she's chinese, so it's okay.
Someone PM'd me to caution everyone about using surnames, i.e. mother's maiden name, on the internet. If you do genealogy, of course, your information is already out there, but thought I'd mention it.
For once I have nothing to add. Many strange or funny people in my family, but their names are somewhat boring. I'm the most normal person that I know.
