How many wives did Robert Fulton have?

His first wife was the late actress Barbara Karen Perk, whom he married in the early 1970s (her credits, as Karen Lamm, include Thunderbolt and Lightfoot). After their divorce, she later married...

He only had one wife, Jean Armour, yet had many casual affairs with many other women.

I am pretty sure Frost had one wive named Elinor White but after her death in 1938 he became infatuated with a Kay Morrison and wrote her one of his most define love poems "A Witness Tree."

Robert Fulton invented the steamboat, allowing for trade to be much simpler since boats were not only able to travel down stream, but they were now able to travel up stream.
