Copies have been made of the information kept by Utah Pioneer companies who came west. This information includes lists of the members of each company and their families, the name of the captain, and the dates the company began and completed their journey. In some cases, additional details were recorded. This information was supposed to be turned into Brigham Young upon each company's arrival. While many of the groups did turn their information in, there were many that did not do so. This collection consists of those records which were turned in for companies who went west betwen 1846 and 1868, and includes more than 15,000 entries.
