In an October General Conference in 1853, Lorenzo Snow was called to help the struggling saints in Box Elder (now Brigham City). He was to choose fifty families to go with him. The Rees family was one of those families.
John D Rees was very active in Brigham City, both in service to the church and the community. He was one of only two home teachers and sent money to help Welsh emigrants. He held many civic positions as well.
From the Biography written about his life, it states:
"In the February election of 1869, six months after his return from Wales, John D. Rees was elected to the city council, and again in 1873. It was during his second term as councilman that he participated in a ceremony at South Willard on February 5, 1874, which celebrated the completion of the Utah Northern Railroad line between Ogden and Brigham City. 'The last spike, which had been made by John D. Rees, was driven in place by Judge Samuel Smith.'"
"In 1875, John D. Rees was elected Brigham City's second mayor, succeeding Chester Loveland. During his term of office as mayor, 'some of the civic accomplishments were the organization of a fire department, fencing the cemetery, parking and planting locust trees from the Courthouse to the West Depot. He set aside parking grounds and gave the city Pioneer Park grounds, specifying that it was to be used as a public park,' As a mark of respect for the gift it was officially named Rees Park. (This in later years was changed to Pioneer Park, and still later, about 1934 to Rees Pioneer Park.)"
