The first Sternwheel Steamboat Stacker Lee was steaming in and about Memphis in the late 1880s, her captain being Stacker Lee of the Lee Line family. There was a third Stacker Lee still steaming around in the 1920s.

Now it's unlikely that this captain was the fella who murdered poor Billy De Lyons. More likely it was a pimp who was nick-named after the steamboat. And whether the murder took place in St. Louis or Memphis is not exactly nailed down.

However, here are some interesting notes from the Lee Line Steamers website:

"The Stacker Lee was named after Capt. Jim Lee's son Samuel Stacker Lee. Stacker Lee served as captain on several Lee boats.   The Stacker Lee was called Stack-o-Dollars by her crew because she was a very profitable boat for the Lee Line. Son Stacker at 16 rode with Nathan Bedford Forrest during the war of northern agression or Civil War depending on your point of view. Stacker was known to live large, pursue women and drink. Later in life he settled down, married and had a son Samuel Stacker Lee, Jr."
