Rothschild (German pronunciation: [ˈʁoːt. ʃɪlt]) is a name derived from the German zum rothen Schild (with the old spelling "th"), meaning "with the red sign", in reference to the houses where these family members lived or had lived. At the time, houses were designated by signs with different symbols or colors, not numbers. The name Rothschild in Yiddish means "red coat" (coat as in heraldic coat of arms). The Rothschild banking family's coat of arms features in the center of its heraldry a red shield.
