Where did Arizona get its name from?

Arizona formally means Arizuma; Aztec Indian, which in definition is referred to as silver bearing or small spring.
Primarily the name was implemented due to a HUGE mine load of silver, 1736; soon to be caved out and resources of silver to be drained from the location (thus draining it of silver).
Prior to the land having no silver, there were a number of debates regarding its name, such as; Arizuma, Arizoner, Gadsonia, Arizona.
However, in 1853 the man James Gadsden purchased a piece of land south of Gila River, hence then in 1863 "Arizona" was primarily formed as it's formal name.
