"Grijalva created the first rancho in what became Orange County," 2 [and was] "a founding father of Orange County." 3 "He was kind of the Pioneer's pioneer [and] was the first to stake a private claim in Orange County." 4 [In fact] "the first adobe building in Orange County, outside the limits of Mission San Juan Capistrano, was erected by the grantee* of Rancho Santiago de Santa Ana, Juan Pablo Grijalva about the year 1800." 5 "The historical traditions of Orange County begin with the San Juan Capistrano Mission and Juan Pablo Grijalva." 3 Unlike most soldiers, he was held in high regard: "Lieutenant Grijalva...fills his post with honor and stands in high repute." 6
The final quote is by Padre Presidente Fermin Francisco de Lasuen. Lasuen founded nine missions, the last of which took away Grijalva's first rancho at Las Flores.
*In actuality, grants were given only in the Mexican period; this was a concession.
