The name of the beautiful valley of Poway (Pauwai) is derived from the language of the Diegueno and Luiseno Indians who roamed the area for several hundred years before the Spaniards came. Traces of these Native Americans still remain.
Documents of Mission San Diego de Alcala record the name of the valley as "Paguay" as early as 1828. Although there is a disagreement on the meaning of "Paguay," the generally accepted translation signifies "the meeting of little valleys" or "end of the valley."
Philip Crosthwaite is believed to have been the first white settler in the Poway area. He built an adobe house and took up ranching in 1859.
A sufficient number of settlers had come into the valley by 1869 to warrant a post office. Castanos Paine, whose ranch was a way stop for stages from the north and from San Diego, applied to Washington for an appointment as postmaster in 1870. The application stated that there were no post offices located between San Diego and San Bernardino at that time. The appointment was granted, but the Postmaster General crossed out the words "Paine's Ranch" and substituted "Poway," thus settling once and for all the spelling of the name.
The 1880's saw a prosperous and well-populated valley. Families were settling on farms, planting orchards and vineyards, and raising grain. Dairying was profitable, as was beekeeping. By 1887, there were about 800 people in the Poway area.
