I have been researching my supposed connection to a Rabbi David ben Moshe and Leah of Kletzk, of Novarodok, (no family name known), and author of a rabbinical treatise "Galya Mesechta" for many years. Recently I have been contacted by a member of this forum who is a descendant of a daughter (first name unknown) of Rabbi David, who married a Yitzchak RABINOWITZ who had two sons, Shmuel and "unknown".
Besides Rabbi David's daughter, he had a son Moshe who married a daughter of a HOROWITZ of Minsk . Moshe, seemingly not having a family name , adopted the rabbinically prestigious HOROWItz name. As the great majority of HOROWITZ s are Leviim, this Moshe is one of the few who are not.
I would be very happy to hear from HORWITZ s who stem from Rabbi David and his son Moshe.
The spelling of HOROWITZ may be variant.
