I did not post the Wikipedia page listed for "Estevanico." It was posted by someone else who keeps rejecting and writing over any attempts to correct the page. Estevanico was the slave nickname for Esteban (full Spanish name of Esteban de Dorantes). The nickname was condescendingly used to demean him, and it is the nickname that is usually used in books mentioning Esteban

The first biography of a forgotten historical figure, Esteban, much maligned when he is mentioned at all in histories of early America, will be published October 15 by University of New Mexico Press.
     When Pueblo Indians say, "The first white man our people saw was a black man," they are referring to Esteban and his arrival in 1539.
