If your ancestors are from General Escobedo, Nuevo, Mexico or if you are doing genealogy research then this free eBook I came across might be of interest to you. It is titled Gral. Escobedo NL. Apuntes Geograficos. Even though it is not an genealogy eBook it does mention historical facts and also several of my ancestors as the Ayalas from el Topo de Los Ayalas and another ancestor Joseph Trevino. I do hope that it is of interest to you.
Another thing make sure to download it since as it is with eBook ont he internet you never know how long they will be available.
