My G-GF Marcus (Mordechai) ROSENBERG, age 60,  appeared on the 1910 US Census in NYC as a rabbi (own account!).  His occupation on the 1915 New York State Census is teacher. I don't know any more about his background.  Is there any way I can find out more about his rabbinical activities?  Are there lists available? I believe he was from the Brody area.
Any help would be greatly appreciated.

Hi Karol,

Here are some ideas.

FultonHistory.com
https://fultonhistory.com/Fulton.html
Free site to search digitized newspapers (heavily New York, but adding papers from other states.)  You can search by name, or by address.  I've found many things in the past by searching on address.

Ellis Island Database
https://stevemorse.org/ellis2/ellisgold.html
Assuming he arrived in port of NY.  You can see what occupation is listed on manifest.

NY and other ports of arrival can be searched for manifests at www.familysearch.org
