R' Ari Liebus HaKohen Rabinowitz, A.B.D. Nowe Miasto-Warszawa, Koniecpol

הרב הגאון המפורסם מו"ה אריה ליבוש הכהן ז"ל, אשר היה אב"ד דק"ק עיר חדש סמוך לוורשא ולסוף ימיו נתקבל לאב"ד בק"ק שדה חדש. הובא שו"ת ברית אברהם חלק או"ח סימן י"ח סכ"ד.

This is the Neustadt aka Novy Miasto, (which was once adjacent to Warsaw and is now part of Warsaw)

This part of the tree is from the book TIferet Shlomo of 1866 written by Shlomo haCohen Rabinovich d1866, (https://www.geni.com/people/Rabbi-Shlomo-Rabinowicz-of-Radomsk-Tife...). He was the grandson of Aryeh Leyb HaCohen Rabinovich and the the grandson of Eleazar HaKohen Rabinowitz. The book was published three years later in 1869. So it would seem this is well within the personal knowledge of the author of Tiferet Shlomo. This part of the tree is based on the following description at the beginning of Tiferet Shlomo.
