From the article:
Then, there's the George Croghan scenario.
He was an Irish fur trader working for England who moved into the Native American territories to trade furs with the Delaware tribe.
He was not born until 1718, which would mean that if built by Croghan, the fort isn't as old as presumed.
Croghan was, I think, a character mentioned in Alan Eckert's 'The Frontiersmen'. Eckert gives plenty of ink to the Iriquois in that, and even more to the Shawnee. But it's really Tecumseh and Simon Kenton's story.
If you haven't read the book (and can withstand the fact that it's a 'historical novel', if not actual fact), it's an amazing story.
