That's great!
1. I was in grade school with a girl named Robin Hood.
2. A former coworker, Randy, had sisters named Candy and Sandy.
3. My aunt named her kids Sherry, Kerry, and Terry.
Not to be outdone:
In my own family, I am David, and I have a sister named Linda. My parents divorced when I was eight, and few years later my Dad remarried. His new wife had a son named David, and a daughter named (you guessed it) Linda.
We never lived in the same house, but for the rest of my parents' lives we were Big Dave and Little Dave (He was older than me, so was Big Dave, although I outweighed him by about forty pounds.) My sisters were "Your Linda" and "My Linda," which worked okay, as long as you knew which side of the family was speaking.
Dave (no longer Little)
