I was raised in Zavala County (next door to Dimmit County, approx. 11 miles away). My maiden name is Loera. I think my family originally settled there in the 1940's but there roots where from San Luis, Potosi, Mexico. I checked our family tree but the names Victoria nor Gertrudis do not appear. There was another Loera family that lived in Crystal City, TX but I was told we were not related to them. Check the census records for that time line in Zavala county. It may yield some information on the other family that lived there. Hope this helps.
