Her mother, Eleonora Dedinszky de Dedina, was a noblewoman of Polish descent[3] whose family had lived in Hungary for centuries.
Her father, Count Agoston Haraszthy, was a titled nobleman who had been exiled from Hungary for "efforts to obtain freedom from what he considered despotism.
"[2] She used part of her increased wealth to have a "colossal villa" built at the corner of Wilshire Boulevard and Vermont Avenue in Los Angeles.
[4] The residence, completed in 1909, included a replica of a "huge carved-wood fireplace" found in a castle in England, a 1865 stained-glass window, and a music salon that contained 18th-century antiques from the Mexican palace of Emperor Maximilian.
Their son, George Allan Hancock, donated Rancho La Brea to Los Angeles County.
