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.
