My family is from Peru and all my life I hear histories about the origin been in the BAsque region. But when one of my brothers joined the Mormon Church, in his research he found out that the origin of our branch is from the south of Spain. Which coincides with another theory that it is an cefeardit lastname. Name given to the jews living in the south of Spain and north of Africa. Also learned that there is a coat of arms of the family and part of the symbols is the water (agua in spanish).
