I am one of Gordon Rhymes Haley's grand-daughters, and I have heard the story that his father (Joel Arthur) was in fact killed, but before I try to reconstruct from memory the details of that story, I need to check in with my mom and grandmother to see what they recall hearing about this event.
I was SO excited to see some of the photos you've posted on the findagrave website. I started doing some ancestry research several years ago, then got off track. On a whim I started tooling around on the internet tonight and nearly fainted when I pulled up the photos of Cammie, by great-grandmother, whom I've only seen in one photo, and also the family photo showing my grandfather as a young boy. Thanks very much for sharing those. Would be interested to find out your connection to the family and how you obtained those cool pictures!
I'll be in touch soon.
