Probably the most interesting thing I've found so far were a series of incidents reported in the Baltimore American and the Baltimore Sun involving my great-grandfather and his first wife in 1904-5. According to the articles, she was quite a violent drunk and often beat the tar out of him. On year on Christmas, she came home pretty drunk and inquired about a missing can of corn. When he informed her that he ate it, she bit his arm which sent him to the hospital with blood poisoning.
Now, from the pictures I've seen and according to my grandmother, my great-grandfather was not a small man, so I can only imagine how violent she must have been. I believe they were divorced no too long after the Christmas incident.
I guess my great-grandfather never talked much about his life before he met my great-grandmother, so my grandmother had never heard these stories before. She got a kick out of these and a couple of other stories I was able to find about about him.
