Hi Sal. I have some additional info on my grandfather's side. Antonino's parent's were Daniel Barraza (b.3/17/1888, in Durango), he was a farmer, and Refugia Martinez (b.7/4/1895, d. approx.1934). Daniel's parents were Adrian Barraza (born in Durango sometime in around the 1860's) and Masadonya Talamantez. I think if there is a link in our families, it might be with Daniel. I am going to try to get information on any siblings that Daniel may have had. My thought is that Daniel and Preciliano might be brothers, which would make your grandfather and my grandfather cousins. It might be a stretch, but I will check it out. Keep in touch.
