Well, so I got a bunch of boxes from my step-mom this weekend. It has a bunch of old stuff from my dad. One box was full of letters from 1943-1945 when my grandpa was in WWII. There are letters to my great-gandma and great-grandpa from relatives I never knew about in Kansas. And there's sympathy cards from when my great-grandpa died, so I learned he was only 59.
The house we live in now belongs to them. It's been in our family for over 100 years, and my dad grew up there. He was raised by his grandma. It's pretty amazing to get to know something about them because my dad's grandma and dad died very close together right before he married my mom. (And his mom was already gone, too.)
