What I found about Monti’s:

Monti’s La Casa Vieja is located in Tempe, Arizona, in the city’s original pioneer home and the oldest continuously occupied structure in the Phoenix metropolitan area. The original adobe hacienda was built as a home by Charles Trumbull Hayden in 1871

HAYDEN, Charles Trumbull
Charles Trumbull Hayden,from Connecticut, had been a trader and freighter in Tucson since 1857 when he left there to establish a farm and flour mill on the Salt River in 1871. As an old freighter, he noticed the need for a dependable way across the river so he put a ferry into service, and the town that developed at that site was known as Heyden’s Ferry. Later the name changed to Tempe at the suggestion of Darrell DUPPA who saw a similarity in the country to that of the Vale of Tempe in Greece.

HAYDEN, Charles Trumbull, Jr.
Charles Trumbull Hayden, born in 1877, was the son of the founder of Hayden’s Ferry. He was a Tempe Councilman, Maricopa County Treasurer, Maricopa County Sheriff, and first elected Representative to Congress from Arizona after she achieved statehood in 1912, and later, the long time U. S. Senator from his state. Carl Hayden U.S. Senator 1877-1969 Carl Hayden was elected in 1911, making him Arizona’s first congressman. He took office the next year when the Arizona Territory achieved statehood. Hayden, a Democrat, became a senator in 1926 and retired in 1968, nearly 42 years later.

Thanks in advance!
