Overview
Anne of Auvergne also known as Anna d'Auvergne (1358 – 22 September 1417) was Sovereign Dauphine of Auvergne 1400-1417 and Countess of Forez in 1372-1417 as well as Dame de Mercoeur from 1400 and 1417. She was also Duchess of Bourbon by marriage to Louis II, Duke of Bourbon.
Life
Anne's mother, Jeanne d'Ussel, died when she was around eleven years of age. Her father remarried two more times; she gained several half-siblings from her father's third marriage to Margaret of Sancerre.
Duchess of Bourbon
Anne was betrothed to her cousin Louis when she was ten years old. The marriage contract was signed at Montbrison on 4 July 1368 and the pair were married in person at Ardes in January 1370. Due to the fact that the couple were cousins, a papal dispensation was required; this was granted to them by the Pope on 15 September 1370.
Countess of Forez
On 15 May 1372, Anne's uncle, John Count of Forez, died leaving no children. Anne was his heir, as all of John's siblings had died including Anne's mother Jeanne and she had been the only one to leave a child, namely Anne. At the time of her accession, Anne was still only a minor (aged fourteen) so her grandmother, Joan of Clermont, acted as regent until Anne reached her majority, at which time she ruled together with Louis.
