I am looking for some information about a great-grandfather of mine or about his parents. He came to Argentina at the beginning of this century and got married and had children. He was born in a little town near Salas the 3/19/1886 and came to América with one of his sisters. His name was Antonio Álvarez and hers was Esperanza. I know that it's quite difficult to find information without having more details of his travel, but I would really appreciate it if somebody could tell me anything about them or about the descendants. I am also looking for the origin of the surname Casaravilla, since I cannot find in any book or heraldry site. Thanks. C.C.
