Kathy: On the same page of the 1930 census that you reference, in addition to Benjamin F. Shockley and his family, there are 3 other heads of Shockley households, Jesse W., Perry S., and Columbus H. They are close in age, all born in Texas and all list father's birthplace as Georgia and mother's as Texas. Now go back one page in the census and you'll see Newt P. Shockley and family living next to Benjamin F. Newt is 63, born in Georgia, and his wife was born in Texas. Common for families members to have nearby or adjoining farms.

Newton is listed in the 1870 (age 4) and the 1880 (age 14) census as a son of Benjamin F. and Rhody Shockley, living in Paulding County, Georgia.

There is a fairly common pattern in this family of naming the eldest son for the paternal grandfather. I think we've just found two more generations of your family!
