Caroline was the daughter of Johann Ignaz Willmann (1739–1815), a musician, playing flute, violin and cello; and his second wife
Marianne de Tribolet, an opera singer. Caroline was the half-sister of
Maximilian,
Walburga and
Magdalena Willmann. After her mother's death, she sang in
Budapest, at
the court opera in Vienna, and in Breslau (now
Wrocław).
Alexander Wheelock Thayer wrote: "Her voice—she was but eighteen years old—was not powerful, but very pure and sweet, except in the middle tones, and of remarkable extent in the upper register." At Breslau, wrote Thayer, "the great beauty of her voice, its excellent cultivation by her mother and Blangini, her fine taste, her charming acting and her beauty, made her a general favourite." Her life after 1825 is mostly unrecorded; she is known to have been a singing teacher in
Bayreuth in 1830. She is thought to have died in Vienna about 1860. ==References==
