I'm starting to feel I should be getting an endorsement fee for
recommending the JewishGen Given Name Database so often (I'm kidding,
JewishGen, no worries).

According to the JewishGen Given Name Database at
https://www.jewishgen.org/databases/GivenNames/search.htm, Shlomo is a
Hebrew name. Schloime (or several other possible spellings) is the
Yiddish version.

Schloime might well have used the patronymic along with his Yiddish
name and his surname because he was most likely known within the
Jewish community as Schloime ben Zindel. Surnames were required by the
Russian government but many Jews used them only rarely, when dealing
with Russian officials, for example. On an everyday basis, Schloime
would have used his Yiddish name and not his Hebrew name, which was
mostly reserved for Jewish legal purposes and solemn events such as
the birth records of his sons, his ketubah, and his being called up to
the Torah.
