Does anyone have any of these?

I found out a few years ago that my Dad's father (who was dead before I was born), was actually married before he was with my Grandma, and also had a whole bunch of kids that he kept secret. My Grandma still refuses to ever talk about it and we only discovered this after the relatives contacted us.

It's very, very weird. It also turns out my uncle (2nd uncle, or whatever the term is?) was also awared a Nobel Prize in Medicine this year! Which is fucking amazing. This is him:

So, not underachieved compared to the rest of my family... much?

Anyone else got any similar stories?
