Let's get historical about Fontana

Here's another city history web page, this one from Fontana:

The earliest recorded landowner in the Fontana area was Don Antonio Maria Lugo, who received a land grant in 1813. A second grant secured the land known as Rancho de San Bernardino for his sons. The Lugo sons sold a portion of their land, which included part of what is now Fontana, to a group of Mormon settlers in 1851. The Mormon settlers eventually returned to Salt Lake City, and the Semi Tropical Land & Water Company gained control of the Rancho. Active development of the area, however, did not begin until the early 1900's when the Fontana Development Company acquired the acreage and began a community called Rosena a name that was changed to Fontana in 1913.
