greeneyes on Family Tree Circles

This four names are the start of my family. They are from Runge, Alice, San Diego and Mexico. My information on them is limited.

I am looking for relatives of Manuel Rios and Dorathea Garza Rios Rodriguez. They lived in Runge, Texas where he is buried in the Mexican cemetry. After his death she married Diego Rodriguez. I want to know who her parents were? Information on Diego Rodriguez. Thanks Christina
