According to the San Mateo County Historical Association: "In 1896, W.H. Crocker commissioned the Sky Farm mansion to be built as a wedding gift for his sister-in-law and her husband. The mansion was later occupied by W.H. Crocker’s son, William Willard Crocker and his family. Today, the Hillsborough mansion serves as home to The Nueva School, a nationally recognized independent school serving gifted children." (See "History Makers: Honoring the Crocker Family,"Accessed 02/08/2011.) Historians disagree about who built Sky Farm #1. Ferol Egon in his book, "Last Bonanza Kings: the Bourns of San Francisco," indicated that "Sky Farm in San Mateo County was originally built for Prince Andre Poniatowski, who later sold it to his brother-in-law, William Crocker." (See Ferol Egan, Last Bonanza Kings: the Bourns of San Francisco, [Reno, NV: University of Nevada Press, 1998], p. 94) Additionally, the Poniatowski House burned in 1928, meaning that the Nueva School occupied a replacement mansion (Sky Farm #2) erected by the Crocker Family. The mining, utilities and water magnate, William B. Bourn II (1857-1936), rented Sky Farm #1 between 1908-1917; Bourn and his family lived here while they waited for their nearby mansion, Filoli, to be built between 1915-1918. (See "Guide to the William Bowers Bourn Family Papers, 1845-1985,"Accessed 02/08/2011.)

Prince Andre Poniatowski financed the construction of the Tanforan Race Track in San Bruno, CA, in 1899.
