Bruno Wolf and his son, Karl Wolf, descendants of Blas de la Garza, father of the Nueces County's first settler, his namesake, and a captain who explored much of South Texas and Northern Mexico, have preserved and guarded Spanish colonial documents for almost 300 years. The collection includes official correspondence to Spain from Mexico, then known as New Spain. Original land grants, research supporting their authenticity, letters that document events of the day, a genealogical accounting of the Garza Falcon family tree and 18th century surveys of areas in what is now Northern Mexico and South Texas. Also included in the collection are legal land dispute transcripts, marriage and birth certificates and many photographs of the Wolf Ranch near Laredo. Bruno Wolf Jr. served in the army during Worth War II; photographs document his time in France.
