Karl Heinrich Marx was born in Trier, Kingdom of Prussia on 5 May 1818, an Ashkenazi Jew, to Hirschel Mordechai and Henriette Pressburg. Marx's Jewish name is Chaim Hirschel Mordechai. Marx descended from Talmudic rabbis; his paternal ancestors had provided rabbis to Trier since 1723, a post last held by his grandfather.
One of Marx's grandparents was Nanette Salomon Barent-Cohen, who belonged to a wealthy Amsterdam family. Her cousin had married Nathan Mayer Rothschild and bore Lionel Nathan Rothschild, "Baron" and Member of Parliament for the City of London.
