SCHULTZ versus SHULTZ

Expanding on my question of historical difference between *SCHULTZ versus
SHULTZ*

T am an English speaker in USA, age 90+ years.

Recently, our USA diplomat *George SHULTZ* died at age 100 years

We often see the spellings --- *SCHULZ, SCHULTZ, SHULZ, SHULTZ*.

Thus, my question of why *SCHxxx*x or *SHxxxx* ---

                USA confusion or European significance.

Google Results for the origins of *SCHULTZ* and *SHULTZ* ---:

       *Schulz* is a common German and Jewish-Ashkenazi family name in
Northern Germany

The German word *Schulz* originates from the local official known as
*Schulthelß* or

(Dorf-)*Schulz*(*e*), a local law enforcement officer like a police
officer, magistrate, bailiff or mayor.

And, so it goes,
