The wikipedia article about King Sancho I of Aragon here:

Sancho Ramírez (c. 1042 – 4 June 1094, Huesca) was king of Aragon (1063-1094, as Sancho I) and king of Navarre (1076-1094, as Sancho V). He was the son of Ramiro I of Aragon and Ermesinde of Bigorre, and he succeeded his father in 1063.
Between 1067 and 1068, the War of the Three Sanchos involved him in a conflict with his first cousins, both also named Sancho: Sancho IV the king of Navarre and Sancho II the king of Castile, respectively. The Castilian Sancho was trying to retake Bureba and Alta Rioja, which his father had given away to king of Navarre and failed to retake. The Navarrese Sancho begged the aid of the Aragonese Sancho to defend his kingdom. Sancho of Castile defeated the two cousins and retook both Bureba and Alta Rioja, as well as Álava.
Sancho Ramírez was elected king of Navarre in 1076 after Sancho IV of Navarre was murdered by his own siblings, thus prompting a succession crisis. Sancho's young son, García, was recognized as titular king in León and Castile, where he lived in exile.
Sancho conquered Barbastro in 1064, Graus in 1083, and Monzón in 1089.
He married first in c.1065 (divorced 1071), Isabel of Urgel (d. c.1071), daughter of Count Armengol III of Urgel and second in 1076, Felicie of Roucy (d May 3, 1123), daughter of Count Hilduin III of Roucy. A third marriage - to Philippa of Toulouse - is sometimes given but other evidence records him as still married to Felicie at the time of his death.
He perished in 1094 at the Siege of Huesca.
His three sons: by Isabel, he had Peter; by Felicie he had Alfonso and Ramiro. All three succeeded in turn to the throne of Aragon.
