In 1881 John married Ida English and built a home in Woodland, Washington. On many occasions Ida would travel with John, even when their children, daughter, Viroqua, and son, Francisco, were born, the family would live on whatever sternwheeler John was piloting at the time. Ida would take the wheel if John was called away on an emergency and provided nursing care to sick or injured passengers and crew. When John began designing his own sternwheelers, he always made sure that a living quarters was built so that his family could accompany him.
