From Shipbuilding History.
Alexander Swift's company built 4 monitors for the US Navy, none of which ever saw service: Catawba, Oneota, Klamath, and Yuma.
In 1871 they built the steamer John T. Moore and 1873, the steamer Alexander Swift (named for himself).
STEAMER JOHN T. MOORE
I found mention of it being used in the New Orleans to Jefferson trade. Not sure where Jefferson is. I also came across the name of John T. Moore as a riverboat captain who died in 1906. Perhaps this is who the boat is named for?
River Boat Dave's site has just about anything you'd need to know about river boats.
According to him, sometime between 1886 and 1892, the name was changed to the Endeavor.
The Moore was a sternwheel, iron-hulled packet, later converted to a side wheeler. Launched 1871 in Cincinnati, Ohio. The hull was said to have cost $30,000 and the whole ship $80,000. It was built for the New Orleans-Red River trade.
There was no mention as to what became of the ship, but it was listed as operating as late as 1896.
