They say that "dead men tell no tales" (and by they, I mean, The Pirates of the Caribbean franchise), but a lot can be revealed about a person, even when they're gone. People leave behind collections, histories, and perhaps most importantly, relationships.
The stories range from the cool to the criminal.
1. From trashpanda4811:
I met all 4 of my mom's boyfriends at her funeral. It was a surprise to them and myself.
2. From The_Mouse_That_Jumps:
My great-grandfather had not, in fact, been eaten by a bear on Mt. Rainier (he was a park ranger). Instead, he’d been cheating on my great-grandmother and was summarily run out of town by her brothers. He moved to Alaska and nobody knew what had become of him until we located his grave, many decades later.
