All the books that exists about this matter, agree on a certain aspect, the name and the catle iron of a farm or stable, are related with its own origin. Whether by the name of the estate, either by a unique element of the estate (tree, path, wellspring, hill, etc,), either by the family name of the owner or farmer, or by the heraldic shield or coat of arms of the family, or by the foreman of the cattle raising, etc. The ORIGIN, that’s what is cool about it, the guiding principle of the tradition. As someone said, son of his times and inheritance of his past.
