Am I a Citizen? Great-great grandparents were German

Hi all - Just checking to see if there's anything I'm missing, but it seems like a straightforward pass down through from my Great-grandfather? Thanks for taking a look.

Great-great grandfather
Born in 1859 in Germany
Emigrated in 1882 to USA
Married in 1881 (wife also German born, in 1856, emigrated in 1883)
Naturalized in 1888

Great Grandfather
Born in 1884 in USA
Married in 1907 (wife has German-born father - haven’t traced that line yet)

Grand Father
Born in 1911 in USA (wife has some German ancestry that is not yet traced)
Married in 1933

Father
Born in 1936 in USA
Married in 1965 (wife has no German ancestry)

Siblings and myself - all born in the USA
