Legitimate children of Ercole: Isabella, Alfonso, Ferrante, Ippolito and Sigismondo had inherited the typical Este nose of their father; Beatrice the slightly upturned one of her mother. Furthermore, all were dark-haired, except Ferrante and Sigismondo, who had recovered, as it seems, the traditional blond of the Este.
