John Rowe Moyle was a stonecutter from Plymouth, England. He sailed to the United States in 1856, after his conversion to The Church of Jesus Christ of Latter-day Saints. Upon arriving by rail in Iowa City, he discovered there were no more covered wagons to be purchased for the trek to Salt Lake Valley, so he purchased a handcart and walked with his family, pulling what few possessions they could bring along. After completing the arduous, dangerous journey, he settled in what later became Alpine, Utah.
John Moyle was later called to work on the Salt Lake Temple, utilizing his skills as a stonemason. He walked 22 miles one way each week to work on the temple, returning home to work on his farm before starting all over again. After losing his leg, he continued to walk on a wooden leg, determined to fulfill the work he was called of God to do.
