Arizona Mining Company. Later the family moved to Ajo where Isabella and John's son, John Selmes ("Jack") Greenway (1924–1995) was born. In 1926, John died suddenly, following surgery, leaving Isabella a widow once again. Isabella and her two children moved to Williams, Arizona, and bought the Quarter Circle Double X Ranch as she and John had planned. Through smart business dealings and the sale of her mining stock at the top of its value ahead of the 1929 stock market crash, Isabella was able to grow the ranch to over . During the same period, she also became the owner and operator of Los Angeles-based Gilpin Airlines. Activism and politics Isabella's political interests and social activism paralleled the interests of her friend Eleanor.
