The discovery of gold at Sutter's Mill in 1848 brought streams of pioneers to California, many of whom were Masons. As early as 1849, Masons from Sacramento-area lodges joined to form a charitable organization, and later a hospital, to assist brothers who arrived in Sacramento exhausted from the hardships endured along the Overland Trail and stricken by the reoccurring cholera outbreaks. In the devastating aftermath of the epidemic, they realized that California Masons needed a facility to care for their widows and orphans.

By 1876 Masonry in California had grown to the point that Grand Lodge launched the plan to provide shelter and protection for Masonic widows and orphans. Masonic Home was built on 268 acres of land at a cost of $33,093. The cornerstone of the original building was laid on October 4, l896 and the Home officially opened on October 12, l898.

The modern Freemasonry society is thought to come from Great Britain during the early 1700’s. The modern society came together when the stonemasons created a Grand lodge in London in 1717. The grand lodge is the main administrative body which governs all lower level lodges belonging to the Freemasons.

Freemasonry fraternity grew rapidly spreading across the world. By 1730, the first lodge was built in Philadelphia, and others were quickly built. Many of the masons were great leaders during the American revolution, such as, John Hancock and Paul Revenues who were members of the St Andrews lodge in Boston. Years later in 1752, George Washington became a member. Over time, the United States have had 13 presidents who have been members of the freemasons.
