My ggrandmother was Getrudes Caldera, Married Vicente Castanon about 1870. Getrudes parents were Ambrosio Caldera and mother Marcos Arcalan. There was another daughter named Gregoria Caldera.
We also had a Vicenta Caldera married to Blas Castanon, parents of Vicente, married to Getrudes Caldera. I know nothing about our Caldera lines in El Durasno, just outside of Jerez, Zac. My hope would be that Ambrosio had brothers and the line continues. Any information appreciated.
