"...She was born in Mannheim, Germany, the daughter of Johann Otto Stamm, a government secretary and Sophia Elisabeth Wimmer. She married Franz Fridolin Weber (1733-1779) on 14 September 1756, and had four daughters: Josepha, Aloysia, Constanze, and Sophie. Constanze was the only one who did not become a professional singer, but, according to Mozart, she possessed a fine voice and musical ear. The children were born in Zell im Wiesental, but the family moved to Mannheim soon after Sophie was born..."
