I was about to post this, decided to check Google, and spotted someone else thinking pretty much the same.
3/10 When One Thing Leads To Another: Patti left a comment that made me curious about the Fort Indiantown Gap, so I did another search finding this buried nugget:
An infamous 19th-century murder in Fort Indiantown Gap resulted in a trial of six defendants who all had blue eyes. They became known as the Blue Eyed Six, given the moniker by a newspaper reporter who was attending the trial. Their murder trial, held in the county courthouse in Lebanon, received worldwide publicity and inspired Arthur Conan Doyle while he was writing "The Red-Headed League".
