" . . . Prime Minister Sharon’s mother has been described on the internet as having been of Subbotnik descent (the Subbotniks were ethnic Russians who converted to Judaism). It is not clear if this is accurate. Available information on his maternal grandparents, including their surname, Shneirov, does not appear to support this statement.

Ariel Sharon's family are Halachic Jews from Belarus.
