I am searching for surnames LUCERO and REY. My gr-grandfather, Ceiro LUCERO, came to live in southwest Texas around 1875 from Chihuahua, possibly from Ascension. I believe he was a little boy of about five years old which means he came with other family members. My gr-grandmother, Paulina REY, also came from Mexico, I think Chihuahua, but my mother said she, Paulina REY, had Cherokee ancestry. My gr-grandparents likely married in Texas, settling in Colorado City, Mitchell County and Van Horn, Culberson County. My mother only remembers that her Mexican ancestry included 'mountain people' of Chihuahua. Any clues for where to start searching in Chihuahua are greatly appreciated.
