Abraham ben Abraham, Polish martyr (born 1700)

Abraham ben Abraham, also known as Count Valentine Potocki, was a purported Polish nobleman (szlachta) of the Potocki family who converted to Judaism and was burned at the stake by the Roman Catholic Church because he had renounced Catholicism and had become an observant Jew. 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.
