Braunschweigisches Adressbuch für das Jahr 1911

Good Morning Good Afternoon:
I am searching sources for: Beke HOLLMANN b 1844, Hinrich HOLLMANN b 1850 and
Johann HOLLMANN b 1856. These people were siblings along with Friedrich
HOLLMANN who emigrated from Germany in 1874. I found a Johann HOLLMANN in
Braunschweigisches Adressbuch für das Jahr 1911, however, I need assistance in
identifying the meaning of the citation. The entry on page 183 is "HOLLMANN-
Johann, Tischler, Kaiserstr.21. II". Would someone explain the "Tischler,
Kaiserstr. 21. II". I will then continue research to determine if this is the
correct Johann HOLLMANN. My goal is to determine if Beke, Hinrich or Johann
married, had children, and if so, did their children marry and have children.
Thank you.
Jon

Good evening Jon,

This means:

Tischler = carpenter
Kaiserstr. 21 = Kaiserstrasse No. 21 (Emperors road No. 21)
II = second floor

Kind regards
