Santso

The origin is dubious. It may be a derivation of “Sanctus,” a Latin form of the name Santo. However, it is also possible it derives from some ancient Iberian name, perhaps of Basque origin, a thesis supported by its spread from the region of Navarre and its extraordinary spread in the Basque country during the early Middle Ages. In this case, a possible etymology could be from “zaintsu / zantsu” (wiry, muscular, vigorous), which in turn comes from “zain / zañ” (root, vein). 1) Sancha of Portugal (1178–1229) was a Portuguese infanta, second daughter of King Sancho I of Portugal, and Dulce of Aragon. 2) Sancha Alfonso (~1013–1067), was Queen de Jure of León from 1037 to 1065 and Countess Consort, later Queen Consort of Castile (1035–1065). She is worshiped as blessed by the Catholic Church.
