The arms are those of Rothschild impaling those of Cohen under an Austrian Baron's coronet, for Nathan Meyer de Rothschild (1777-1836) and his wife Hannah, 3rd daughter of Levi Barent Cohen of London. They were married October 22, 1806. Nathan Meyer, the 3rd of Meyer Amschel Rothchild's five sons, was head of the London branch of the family's banking business which staked its fortunes on the success of the British against the French in the Napoleonic Wars. For their services to the Austrian Empire, all five brothers were created Barons of Austria in 1822.
