I am the wife of an Unzueta from Juarez, Mexico. His father is Martin Unzueta Castillo. (where Castillo is his mother's madien name). I am researching our family tree and am looking for anyone who may have information on where to locate records from Mexico and Spain. My husband's great-grandfather was from Spain and supposedly from a wealthy family. He would have migrated to Mexico in the late 1800's or early 1900's. Just post any responses here. Thanks.
