Margaret of Prades

She was the daughter of Peter of Aragon, Baron of Entenza (1352–1395), and his wife, Joan of Cabrera.

On 17 September 1409, Margaret married Martin of Aragon, a second cousin of her father. The bride was about fourteen years old and the groom fifty-three. Martin had survived all his legitimate children from his first marriage with Maria de Luna and was in need of a legitimate heir of his own. On 31 March 1410, Martin I died after six months of marriage. They had no children. His death led to a two-year interregnum, which was ended by the Pact of Caspe, in which Ferdinand I of Aragon, younger son of his sister Eleanor, was chosen as the next king.

Margaret remained a widow for about four years. She married her second husband John of Vilaragut in 1415. In secret, she gave birth to a son in 1416, whose name was Joan Jeroni de Vilaragut (1416–1452).[2] John died in 1422 and Margaret entered the monastery of Bonrepòs. She died in 1429.
