The Blackner Cabin was the home of John and Hannah Blackner and their 14 children from 1898 to 1916. Six of their children were born in the log home.

In 1897, along with 6 other families, John Henry Blackner and Hannah Eyre Blackner left Minersville, Utah in search of better economic conditions. Their party left Utah with 13 wagons, 3 buggies, 30 work horses, and about 140 cattle. Sam Strong, having been hired to serve as their pilot, lead the Blackners and their party to Lyman, Wyoming.

In the spring of 1898 the cabin was built by John Blackner, his older sons, and some family friends. During the first winter the cabin had dirt floors and no windows. They had a Majestic cook stove for heating and cooking. In 1899 windows were put in and the following year floor boards were laid. The out house was a one-seater in front of the house. It was surrounded by trees. Little time was allotted for reading the Montgomery Ward Catalog as 16 people kept its door revolving.

A coral was built to the back left of the cabin and is where John Blackner kept his 2 Belgian Stallions and his work horses. Some of the work horses were sold to a nearby coal miming company. The work horses were lowered down into the coal mines where they stayed until they died.

The Blackners lived in the cabin for 18 years, making a living primarily by farming. They moved out of the cabin and closer to town in 1916. At that time the cabin was given to daughter Drucilla Rollins.

During the past several years, until Nauvoo Log Cabins obtained possession of it, the cabin was used primarily for calving cows.

Leonard Blackner (second row and third form the left) was the first mayor of Lyman. He helped to bring electricity to the town and was co-founder of the Union Light and Power Company.
