Following, they bought a farm in the southern part of Grantsville, and there, they had four more children. Six years later, they bought another home, although they tore it down and rebuilt it, living in a kitchen and tent while it was under construction.

Part of the J. Allen Parkinson collection, this is a six-page autobiography, compiled and written in part by Kathleen Clark. It is located in the fourth folder of the collection, which is labeled, Biographies, CA-CU. In the manuscript, Mary recalls taking first prize at a city fair when only seven or eight years old; when she was fifteen, she received her Temple endowments, and when seventeen, she had spun enough yearn to make a dress and two suits for her brothers. She also helped make men's shirts to be sold. She visited her brothers frequently in St. George and Grantsville, and she was active in the LDS Church. She sang in the choir, and she provides details of some of the singing parts she had. Mary writes further concerning various sicknesses her children faced, such as whooping cough, mumps, measles, chicken pox, and scarlet fever. She and Joshua had a total of ten children, and she writes about their marriages, activities, and deaths. For her and Joshua's Golden Wedding, they held a party in their summerhouse. After this point, the autobiography switches into a biographical standpoint, as Kathleen writes that Mary had a wonderful life. She also writes that Mary comes from a long line of ancestors, which includes a heritage of fifteen kings and a queen. She concludes the manuscript by writing, Most of this story is taken from an autobiography written a few months before she[Mary] died. Kathleen writes that she tried to write the biography, as Mary would have told it. The relationship between Kathleen and Mary is unclear.
