As the Joseph Smith Sr. family continued to move from place to place, they came to settle on the farm of Lucy Mack Smith's father, Solomon Mack. They apparently stayed in his home after he moved to a different one on the same property. Joseph and Lucy Smith were the parents of three living children when they moved to that rented home on Dairy Hill. The Prophet Joseph Smith himself likely had no personal recollection of the site because his family moved to another home when he was very young. But his nephew, President Joseph F. Smith, authorized Junius F. Wells to purchase what was once the Mack farm, including the birth site of the Prophet. In 1905, a memorial cottage and impressive monument were then erected at the site. Both were dedicated by President Smith on Dec. 23, 1905, the 100th anniversary of Joseph's birth.
