The land that makes up Wayne County was originally part of Piute County.  Wayne County was officially organized on May 2, 1982. Wayne county was named for the son of a delegate to the constitutional convention, who was dragged to death by a horse. 

The town of Crosby is the county seat of Divide County, North Dakota, noted for being the northwesternmost county in the state. The population of Crosby is about 1,000. The total population of Divide County, per the 2000 US Census, was 2,283. Just under half the county residents live in Crosby. There must not be much happening outside of Crosby.

Divide County is, in fact, on the border of Canada to the North and Montana to the west. Divide County was carved out of Williams County in 1910. The County name is not an accident - the county was formed when Williams County was DIVIDED; the county straddles the continental DIVIDE, and sits on the DIVIDE (ing) line between Canada and the United States. Somebody had some fun with that.

I have to say this is one of the prettiest county courthouses I have had the pleaseure to visit. No doubt I say that because I happened to visit in the late afternoon, which provided beautiful lighting. 

Towner County was organized in 1883, along with nine other counties, six years before North Dakota was officially granted statehood.  The county was formed from a resurvey of Cavalier and Rolette counties and was named after O.M. Towner, a  member of the 15th territorial legislature. The new county ended up with a total area of 660,480 acres. The county seat is Cando.

Towner County came to be settled in earnest in 1883 and 1884, and continued to see strong settlement and peaked in 1910 with a recored population of 8,693. Since then the population of Towner county has slowly, steadily declined. As of 2000 US Census, the population of Towner County was 2,876.

The following story is chronicled on the Towner County website (https://mylocalgov.com/townercountynd/WebSubsection.asp?key=19), and tells about how the location of the county seat and the name of the township which would host the new County's Courthouse:

'In December, 1883, with a gray blizzard in the air, Andrew Gerrard, the blacksmith, blew up a blazing fire and arranged boxes and kegs for the first public meeting in the county. There were six residents from the banks of the big coulee to the East who arrived first and so far took the blacksmith into their confidence as to confide to him their purpose of establishing the county seat near their properties, but they reckoned a little wrongly. A motion was made by Mr. Conyers that the county seat be placed just where they were then sitting, but the six from the coulee most emphatically stated that the county seat could not and should not be placed there, and every effort was made by them to have it located on the town-site already located on the bank of the coulee. The meeting had lasted for several hours when Capt. PARKER, who was chairman of the board, arose to his feet and shouted, "They say we can't do it and we say we can do it, and just to show them we can do it, we'll call the county seat CAN-DO!". The motion was heartily seconded by the other commissioners and supported by their friends--and so the town was named. (Towner County Democrat)'

Rosebud County Montana was formed in 1901 from land carved out of Custer County.  Rosebud County is located in the southeastern part of the state and is near the Wyoming border. The town of Rosebud parallels the south shore of the Yellowstone River, ten miles east of Forsyth on Interstate 94 and Route 446. 

The Rosebud County Courthouse was built in Forsyth in 1912 after a bond issue passed.  The total budget for the land and building was approximately $107,000. The total cost of the building, including furnishings, came to almost $175,000 - about $50,000 over budget.  Legend has it the contractors locked the door and wouldn't let anyone in until it was paid for.  The Judge at that time allegedly called a Grand Jury, put the contractors in jail and eventually the courthouse was opened.

During a severe flood in 1919, the courthouse was one of the few places in the county that did not suffer significant water damage.

The Rosebud County Courthouse was added to the National Register of Historic Places on April 17, 1986

This area was explored by fur trappers and traders, with nearby Rosebud Creek popular for beaver. On July 28, 1806 William Clark & Company passed the Rosebud creek area.

During the 1860's and '70's the area was popular with buffalo hunters, who took thousands of robes. The wreaked havoc among eastern Montana's Native American tribes and precipitated several years of bloody fighting, culminating in the Battle of the Rosebud on June 17, 1876, and the Battle of the Little Bighorn eight days later.

The Rosebud Battlefield State Park is a 3,000-acre prairie park which preserves the site of the June 17, 1876, battle between the Sioux and Cheyenne Indians and General Crook's soldiers.
