SOTOMAYOR, Cristobal de (so-to-mah-yohr'). Spanish officer, born in Spain in the last quarter of the 15th century ; died in Guanica, Porto Rico, 25 July, 1511. He arrived in Santo Domingo with the expedition of Diego Columbus in August, 1509, and the same year went to Porto Rico with the expedition of Juan Ceron, who had been appointed governor. In 1510, when Ponce de Leon obtained from King Ferdinand the appointment of governor of Porto Rico, Sotomayor entered his service and became his lieutenant, assisting in the foundation of Caparra and the conquest of the island. Toward the end of 1510 he discovered on the southwest of the island a great bay, on the coast of which he founded the city of Guanica, from which that bay afterward took its name. One year afterward he founded on the north coast another town, which was called after his name, Sotomayor. In 1511, when the cacique Agueynaba, aided by the Caribs, revolted, the city was surprised during the night of 25 July and set on fire, and Soto-mayor, after a brave resistance, met his death with the greater part of the garrison.
