I am seeking information regarding the surname, Elorreaga. Where does it originate? Religious background? How and when did the ancestors immigrate to the states? Some claim they were Jewish and changed their name due to the Spanish Inquisition? Is it true there is a chocolate factory with this surname? What are common physical features from this lineage? Please....any information you can assist me with would be most helpful. I have been searcing for this information in vain.
