I've never met my grandfather. He died over 10 years before I was born. He died when my mom was 13 so she knew very little about him. It's amazing what you can find on the internet these days - we had no idea that his bachelor's was in philosophy even though he ended up being a rocket scientist. We had no idea that he had been an education minor and then dropped it, and we had no idea he won three athletic awards when he graduated (his athletic nickname was "Mumbles"). He graduated in 1950, planning to become a priest, and became a rocket scientist instead.
We also found a bit about his brother that graduated in 51 and died in 54. :( Sad times.
