my sister is going thru the same. it is very difficult to locate by name in spain.these names you posted are very very common. the trick is to get both of your mothers parents name...then her name would be EG: sue (fathers last name)(mothers last name)my sister and i have been to madrid twice looking for info. even with family there they are very tight lipped espicially the older generation.be patient and persistant.there are records out there.we found an original bith certificate that was supposed to be destroyed and replaced with one from the ;;;;;;black market???
