I'm wondering if anyone know where Margo's Saloon was located in Rio Grande City, Texas! What business might be occupying Margo's Saloon right know???? My Great-Grandfather, Juan Morales along with his brother, Gabriel Morales and Sheriff Deodoro Guerra were accused and charged with murdering former Tax Collector, Gregorio Duffy in 1908!! I'm trying to locate the location where Gregorio Duffy was killed in Rio Grande City, Texas, Margo's Saloon! If anybody has any recollection or whereabouts where that building was I would like to hear about it........Thanks!!!!!
