There's several sources pointing out that Loyola was a Basque racially. Not only did he mention that he wished he was the "same race" as Jesus, (not neccesarily "Jewish" but probably Semitic in origin) but Ignatius belonged to a noble family located in northern Basque, a somewhat isolated place from migrants.

The Journal of the Anthropological Institute of Great Britain and Ireland, Volume 5, page 18, mentions that Loyola, Xavier among other members of the original Jesuits were racially Basques, and Loyola's ancestors were DNA tested, and he, being a Basque, was R1b, not J1 or J2, surely not being semitic.
