I think I am on the right family but if your father is alive, or some aunts and uncles you might want to ask a few questions.There was only one Navarro family in Gonzales county in 1930 and that was a Pedro. Notice that there are two Navarro families in the 1930 census.I think they are the same family but counted twice.Zapata and Webb are adjoining counties. I found this family in the Texas Birth Indexes 1926-1949.Amador and Simona (Longoria) Navarro had Simona, Marta, Doris, Ramon, David, and Oscar in Webb county 1927 to 1941.Simona middle initial was "P" one time and "L" another time.For some reason, your father wasn't listed but he is in the census.

Finding Amador Sr. in earlier census will be difficult.
