I also have a Rabinowitz family from Vilna. Schai Rabinovitz-Louis, a Rabbi married Fanny Kossak. Their son who called himself Michael Louis was born 1859, Vilna, Russia.Michael came to Australia. His sister was known as Fanny Levy or Louis may have died in New York or New Jersey area.His brother Mosa was living around 1928 in Letuwa, Europe. Another brother Alec Rabbinowitch was living around 1928 in New York, USA. Has anyone come across any members of this family?
