Other evidence of Jewish ancestry is language. According to a Jewish genealogy blog, New Mexican Spanish, a Spanish dialect spoken by many of the old families of northern New Mexico and southern Colorado—and chiefly only among themselves—appears to be a form of Ladino or Judezmo. This was a hybrid language that developed among Sephardic Jews in Iberia, from Old Spanish, Portuguese and Hebrew, with sprinklings of Arabic, Greek and other languages, depending on the geographic region of the speakers or their ancestors.
