Because the Lewis and Clark boat was built in Pittsburgh and many believe it was built in McKeesport.It's true that other Historians feel it was done at Ft Fayette in Pittsburgh and others feel it was built in Elizabeth PA.
What's for sure the first stop was Brunot Island just off McKees Rock and is noted in Meriwether Lewis' logbook.It's the second entry after he picked up his boat which was the first entry.
My center is John McKee and all the people around him at Versaille Cemetery in McKeesport.He was a riverboatman who owned a ferry in a small port.Many people called it McKee's Port.The name stuck.None of the people buried around him have a history.Pull a name, do a google and nothing.It's as if they never lived.Go to the next and nothing.This is not all the case such as Daniel Pollard about 30 ft away.A riverboat captain who was the flag ship captain for General Grant.The Olivers, 20 ft away, who supplied wood for Robert Fulton's steamboat The New Orleans.Robert Fulton built that boat personally with his business partner Robert R Livingston.The Clarks near the Pollards were in the boat business with the Lewis family building boats in McKeesport in the late 1790's.You know, people like that.
By coincidence Robert R Livingston was the chief negotiator with Bishop Talleyrand for the land Lewis and Clark were going to explorer.They along with the Hue are also up at Versailles with the Gallatins. Then Robert Livingston's sister was married to Robert Fulton.
What's interesting is these no history people seem to be connected to Albert Gallatin who had a farm near the home of Robert Fulton.Albert Gallatin tried to evaluate families living at Versailles France in 1794. It's a well recorded event and discribed in a book about Marie Antoinette's daughter.
I have extensive records on Versailles Cemetery on the old section which is sections A to F.
