Bluff in San Juan County, Utah — The American Mountains (Southwest)
F.I. Jones & Mackelprang Families
Their family grew to include three more children while living in Bluff. In 1886 they were asked to help establish a settlement at the northeast base of the Blue Mountains, which became Monticello. Fredrick was the new community's first bishop, a calling he served in for 21 years. Mary was president of the Relief Society (the Church's women's organization) for 23 years. Mary is remembered for her unselfish service and generosity.
According to Albert R. Lyman," [Their] little log home, and later a large brick house, was a hospitable refuge for both friends and strangers.... He [Fredrick] deserved a degree as farmer, builder, diplomat, pioneer. What he lacked in what the conventional school could give, was more than compensated for by his good common, reliable horse sense." They had six more children in Monticello. Of their eleven children, nine lived to adulthood.
William and Adelia Mackelprang Family
Mary Jones' brother Samuel William Mackelprang, known as William, and his wife Adelia Terry and five children were among the original pioneers who came to Bluff via the Hole-in-the-Rock in 1880. Adelia gave birth to their sixth child in a wagon box shortly after their arrival. Two more children joined the family while at Bluff. William was a carpenter and also hauled freight. In exchange for food, Adelia used her weaving and sewing skills to make hundreds of velvet ceremonial clothing for Native Americans. They moved to Huntington, Utah in 1884. Three months following the birth of their tenth child, William died at age 39. Adelia supported her family by taking in laundry. Their ten children all lived to adulthood.
Christian Eric Mackelprang, another brother to Mary, was called to the San Juan settlements in 1882. He helped establish the first orchards in Bluff.
