On the day, 15 October 1173, Petronilla of Aragon passed away. She was my three-times 27th great-grandmother.
Born on 29 June 1136, in Huesca, Spain, Petronilla was the only child of Ramiro of Aragon and his wife Agnes of Aquitaine.
Prior to his marriage to Agnes of Aquitaine, Ramiro of Aragon had been the bishop of Barbastro-Roda, When his brother, Alfonso I, died in 1134 without an heir, Ramiro was elected as ruler. Ramiro sought papal dispensation to abdicate his monastic vows in order to secure succession to the throne. After he received dispensation, Ramiro of Aragon married Agnes of Aquitaine in 1135.
