"In 1785, Spanish explorer José de Evia, during his own charting of the Gulf Coast, referred to the island as "San Luis" and the bay as "Bahía de Galveztowm" [sic] ("Galveztowm Bay"), in honor of Bernardo de Gálvez y Madrid, Count of Gálvez.The name San Luis for the island continued to be used by the Spanish and the Mexicans (and later even by Stephen F. Austin's colony), and is still used as the name for the pass at the west end of the island.
