In 1854 Samuel McCorkle platted the town of Somerville. When the Hannibal and St. Joseph Railroad (a line whose founders included the father of Mark Twain and which was to deliver the first mail of the Pony Express) proposed coming through the area, the line said the area around Somerville was too steep for the rail so he platted a new community 1.5 miles to the west in what is now "Olde Towne" Cameron. The town platted in 1855 was named for maiden name of his wife Malinda Cameron. McCorkle Park is still Cameron's centerpiece park.
