Yep - they are, and were odd. I'm quite open about this (although my Mum thinks its shameful), but my Dad's parents were first cousins, which made his parents his second cousins, and means I was related to them in a weird cousiny type way as well. The weirdest that they ever were at my Dad funeral. They just ignored my Mum and my Grandma acted like some grieving widow. It was just awful. Guess that's what it's like in rural Durham!
