I'm researching my dad's family and am having trouble with finding information about them. I've tried all their names in Ancestry.com's database and I'm at a dead end. I've tried the Papago indian indexes. I also tried on Arizona's genealogy site with no luck either. My dad wants to know when his family came to Mexico from Spain. I tried a website from Spain but it's kind of hard to understand with my rusty college Spanish. So far, this is what I have:
My Dad's Dad: Antonio Noriega B. Tucson 1897, died Burbank 1937.
Antonio Noriega's dad: Jesus Noriega b. Feb 1870 Sonora, MX, immigrated 1878, died 1913.
Antonio Noriega's mom: Concepcion Castro b. 1880 Tucson, Arizona
Concepcion Castro's dad: Jesus Castro B. Dec 1852, Sonora, MX
Concepcion Castro's Mom: Eugenia Arvizo Castro Brown b. 1855 Altar, Sonora, MX immigrated 1874.

My dad's Mom: Felicitas Soto B. 1902 Tucson, AZ died 1990 Burbank
Felicitas Soto's Dad: ????? Soto
Felicitas Soto's Mom: ????? Estrada
Felicitas Soto's Grandma: Felicitas Estrada b. 1885 Sonora, MX

They stayed in Tucson as far as I know, but I can't find any records of them at all. I have my grandparents marriage certificate and my Uncle who was born in Tucson, birth certificate, and record on the 1920 Census showing my grandma, age 17, living with her grandma, Felicitas Estrada
that is all. Any help you can give me would be greatly appreciated. Thanks!
