William H. Jones and his son Arthur H. were both born in Wales; William in 1855 and Arthur in 1876. William lived in Minneapolis and worked as a stone cutter on the Capitol in 1898 and 99.

Arthur H. Jones and his father, William Harry Jones both born in Wales, 1887 and 1855 respectively, lived in Minneapolis but came over to St. Paul to work as stonecutters on the Capitol. The family had been stonecutters for generations and William’s father had supervised stonecutting at Buckingham Palace. A third member of the family, Allen Jones, William’s brother, also worked at the Capitol as a stonecutter. William was an active union member and served as delegate from Minneapolis to the union’s 1890 convention. Like many stonecutters William was disabled by silicosis and he retired from the trade in 1910 and worked in the Minneapolis police department before succumbing to the disease in 1914.
