HI,there were jewish people in spain at that time.Many were "conversos" during or before the spanish inquisition and expelled or forced to become catholics.Arroyo according to Sephardim.com and the registro officiale of rome accepted arroyo as a sephardic jewish surname,sepahardi meaning comning from spain.I come from the Arroyo_Gely_brugman and salazar family.
