Hola "Primo", I have Esteban Anda Altamirano as being born in 1574 in Sta Maria de Los Lagos, Jalisco - married to Catalina Lopez de Portugal abt.1610 Children: Pedro Anda-Altamiano Gomez de Portugal, Maria Altamirano, Beatriz Altamirano and Esteban Anda Altamirano Gomez de Portugal b. abt 1618 Lagos de Moreno, Jalisco Do you have any others??
Several places I have checked show Pedro Anda Altamirano as born about 1551, his parents Pedro Anda and Isabel Altamirano married about 1550 in Spain. In a DeAnda family tree I found it shows the fatherof Beatriz Gonzales de Castaneda b. abt 1556 (wife of Pedro "Jr") as being Pedro de Castaneda. There is a Pedro de Castaneda who was part of the Coronado expedition in 1540 into what is now the southwest area of US. Pedro de Castaneda had about 8 children and at the time of the expedition was living in northwest Mexico. There are several books on Pedro Castanedas first hand account of the expedtion. I need to do some research on this.
The posiblity that Isabel Altamirano and Hernan Cortez's mother being related is facinating. I will have to followup on that also. Let me know if you find anything. Thanks Aurora (from Temecula, California)
