Meagher County as described in 1939 
Meagher County was named for General Thomas Francis Meagher, an Irish patriot and Civil War hero who came to Montana as a Federal official. Acting as Territorial Governor in the absence of Sidney Edgerton, General Meagher made a trip to Fort Benton, July 1, 1867, intending to go down the river to obtain arms for a campaign against the Indians. Late at night, on the eve of his expected departure from Fort Benton, he went to his stateroom on the steamer after a visit to a tavern, and was never seen again. For some time rumors were afloat that the general had been pushed into the river while attempting to board the steamer, but this was denied by responsible citizens of Fort Benton who had escorted him to his room. He was a large, powerful man; it is improbable that he could have been forcibly taken from his stateroom and hurled into the water without a struggle that would have aroused the crew and passengers. What happened to him remains one of the mysteries of pioneer Montana.
