Lewis Leonard Bradbury (circa 1823-1892), originally from Bangor, Maine, moved to Rosario, (Sinaloa) Mexico in the early 1860s.
He began accumulating shares in the "Tajo" mines, eventually gaining controlling interests in 1873. He married Simona Martinez
in Mazatlan, Mexico around 1867. In 1880, L.L. Bradbury moved his family to California, first settling in Oakland and then
Los Angeles, where he began investing in California real estate. Around 1883, he acquired Rancho Azusa de Duarte in southern
California which is now part of the present-day cities of Duarte and Bradbury (both incorporated in 1957) in Los Angeles County,
California. Lewis Leonard Bradbury died in 1892.
Lewis Bradbury, Junior (circa 1881-1948) assumed control of the family business in 1902, and the Bradbury Estate Company was
incorporated in 1904. Subsidiary companies were accumulated and created, beginning in 1910 with the purchase of the Bolaños
Mining Company and the incorporation of the Mexican Mines Company (1910), the North American Venture Company (1910), and "Lewis
Leonard Bradbury and Company" (1916). Other subsidiary companies in Mexico included Compañía Minera del Pacífico (1926) and
Compañía Minera del Cañon de Bolaños (1926).
Inter-familial litigation took place between the six children and various grandchildren of L.L. Bradbury between the years
of 1932 to 1938, in response to business and financial management practices and the disbursement of funds. The business and
mining success of the Bradbury Estate Company declined thereafter. In 1956, Marion Winston Jenkins (niece of Lewis Leonard
Bradbury, Jr.) arranged a contract and purchase option agreement with the San Francisco Mines of Mexico, but the sale was
never culminated. The Bradbury Estate Company was dissolved in 1965.
