I have relatives in Fronton, Texas. I am also looking for my grandparents roots.My gparents were Praxides Guerra married to Luz Perez and they lived in Fronton until about 1925 or so. They moved from there to San Juan, Texas. Any information about Luz Perez, whose parents were Eulojio Perez and Antonia Trevino, is greatly appriciated. Her sisters were Maria Perez married to Valentin Guerra. Clotilde Perez married to Santos Barrera,and Paula Perez married to Toribio Rojas.I believed she had a brother Felix Perez but I am not sure.
If we go to the Valley I will try to visit Fronton and will asked questions about your surname Menchaca. I will keep in touch with you.
