As you said, Capt. Joseph Marie LaBarge married Eliza Palagie Guerette.One of his younger sisters, Mary Louise LaBarge married Eliza Palagie's younger brother Louis.
When the Saluda exploded, both Capt. Joseph Marie's brother Charles and Mary Louise's husband Louis were killed.They were 1st and 2nd Pilots, respectively.There is a very intersting description of the event written by the Mormon Historical Studies which I have posted on: www.laberge.infoI have also posted my gedcom file there if that is of help.
I have hi-lited some points.Note page 48 where it states that "By far the deadliest risk in steam boating was the boiler explosion".
The story of Capt. Joseph Marie LaBarge is just so amazing.You should read the biography by T.S. Bowdern if you haven't already. He was recognized as the most famous riverboat captain, taught Mark Twain about it, fought indians, and knew Brigham Young and Lincoln, and I am sure anyone famous who traveled on his boats up the Missouri on their way west.
I found this interesting:
On October 1, 1859, Joseph LaBarge celebrated his forty-fourth birthday by taking his new steamboat, the Emilie, on her maiden voyage. Designer, builder, owner and pilot, the captain named the vessel for one of his daughters.
The Emilie's most famous passenger was Abraham Lincoln. In modern Council Bluffs, a monument marks the spot where Lincoln stood in August, 1859, and looked out over the majestic Missouri River Valley. He gave a speech, examined some real estate and conversed with General Grenville M. Dodge, just returned from making surveys for the route of the Union Pacific Railroad. Later, when Lincoln was president, and because of these talks, he decreed that the Union Pacific should start in Council Bluffs instead of Omaha.
A great book on the subject is: "Nothing Like It In The World: The Men Who Built the Transcontinental Railroad 1863-1869".I highly recommend the audio book.
One should note that Capt. Joseph Marie's brother John Baptiste was a partner with his brother and equally talented.
