Abraham ben Abraham

Abraham ben Abraham, also known as Count Valentine Potocki, was a Polish nobleman (szlachta) of the Potocki family who converted to Judaism and was burned at the stake by the Roman Catholic Church for apostasy. According to Jewish oral traditions, he was known to the revered Talmudic sage, the Vilna Gaon, and his ashes were interred in the relocated grave of the Vilna Gaon in Vilna's new Jewish cemetery. Although the Orthodox Jewish community accepts the teachings about Abraham ben Abraham, including the involvement of the Vilna Gaon, secular scholars have so far concluded the story is apocryphal.
