Yes...need to find my great, great granparents. My great grandparents came in 1890 to Texas don't know from exactly where in Mexico..either chihuahua or coahuila...not sure

Anyways I'm looking for records starting with Eugenio Orona born April 1858 and wife Estanislada Solorio born March 1864 I want to know where they came from and thier parents and so on...

Please help!

p.s. how come there are not many records on Mexico?...so frustrating !
