Short, plumb, and blonde with slightly bulging blue eyes, Louise resembled her father. She was witty, chatty, and with a strong character. She liked music, playing the harp, and singing. She adored her brother and they were very close. Both siblings became attached to their aunt, the Duchess of Angouleme, who, although severe, was devoted to them. They annually received the visit of their mother, the Duchess of Berry, who lived nearby and provided them with four half-siblings. After the death of their uncle the Duke of Angouleme in 1844, the siblings moved with their aunt to Schloss Frohsdorf, a baroque castle just outside Vienna.
