search help

hello, my name is Delia Dominguez, a new member to nuestrosranchos. i need help in understanding how i can use the resources at nuetrosranchos. i am looking for ancestors in Aguascalientes, but specifically my maternal grandmother, Maria Reyes Rodriguez, born about 1894, possibly in Rincon De Romos. i have been able to locate her parents and grandparents, as well as two of her brothers through Familysearch. but not her. can you give me direction or resources i can access.
respectfully,
Delia Dominguez (Duran)
