Castanon in Valparaiso, Zac

Barbara my Castanon line came from Valparaiso, Zac to Jerez, Zac in abt 1750 but I haven't found any records for them before that. I do not have the Gertrudis Castanon you ask abt in my records. I will let you know if I ever find the records for the earlier years in Valparaiso.
