Lewis Ainsworth (1829 - 1914) and his wife Persis (1837 - 1933) chose Orange as their home in 1901 after making their fortunes panning gold in California and farming in Kansas. They raised three sons, Lewis, Frank, and Mitt, and two daughters, Eva and Ina. Frank served as mayor of Orange from 1918 - 1920, and Mitt was a councilman from 1922 - 1926. Lewis built the Ainsworth Block on Plaza Square in 1907 and founded the first lumber company in Orange. Their house, designed by their daughter Ina Butler and built in 1910, reflected the simple life of the elderly couple, and its restoration was initiated by the Orange Bicentennial Commission and Councilman Don E. Smith. The home is listed on the National Register of Historic Places.
