María Díaz I de Haro
María
Díaz I de Haro" the Good"( b. 1254–1342) was a Spanish noblewoman of the House of Haro.
She was the daughter of Lope Díaz III de Haro who was assassinated by order of the king at Alfaro, La Rioja.
She is best known for being the Lady of Biscay and for her lifelong battle against her uncle, Diego López V de Haro for the title of the lordship of Biscay.
Violant of Castile
Violant of Castile( 1265–1287/1308), infanta of Castile and Lady of Biscay on her marriage to Diego López V de Haro.
She was the daughter of Alfonso X of Castile, and Violant of Aragon.
Fernando Díaz de Haro (Lord of Orduña and Balmaseda)
Fernando Díaz de Haro was a Spanish noble of the House of Haro.
He was the second born son of Diego López V de Haro, the Lord of Biscay, and his wife, the infanta Violante de Castilla y Aragón, daughter of Alfonso X of Castile.
Fernando became lord of Orduña and Balmaseda in 1322, after the death of his brother, Lope Díaz IV de Haro who died without leaving any descendants.
Diego López I de Haro
Diego López
I de Haro (died 1124×6) was the third Lord of Biscay, and also the ruler of Álava, Buradón, Grañón, Nájera, Haro, and perhaps Guipúzcoa: the most powerful Castilian magnate in the Basque Country and the Rioja during the first quarter of the twelfth century.
He was a loyal supporter of Queen Urraca and he fought the invading armies of her estranged husband Alfonso the Battler on two, or perhaps three, occasions.
Diego succeeded his father, Lope Íñiguez, in Biscay (and perhaps Guipúzcoa) on the latter's death in 1093, but Álava went to his brother-in-law Lope González.
On the death of García Ordóñez at the Battle of Uclés (1108), the "tenencias" of Grañón, Nájera and Haro passed to Diego by an act of Alfonso VI.
In June 1110 Diego received a grant of privileges from Queen Urraca, acting without the consent of Alfonso the Battler, whereby she gave all his patrimonial lands (that is, lands he owned, not fiscal lands he governed on behalf of the crown) complete immunity from confiscation.
In August Urraca, then advancing with her army on Zaragoza, confirmed some rights and privileges of the monastery of San Millán de la Cogolla, an act confirmed by the three most important magnates of the region:
Sancho, Count of Pamplona, Diego, described as "senior in Nagera", and Íñigo Jiménez de los Cameros, "dominante" in Calahorra.
At that time Íñigo Jiménez was also ruling Buradón.
After Lope González's death in 1110 and before 1113 Diego succeeded to Álava and re-united all his father's "tenencias".
It was Diego who first began using the toponymic surname "de Haro", which became the family name.
It is possible that Diego, alongside the Navarrese count Ladrón Íñiguez, first went to war against Alfonso in 1112, and that there was fighting in the vicinity of Castrojeriz that July.
Alfonso made reference to Diego and the fighting in a charter to Santo Domingo de la Calzada, but this charter is dated differently in each of its surviving copies.
One copy dates it to July 1124, which fits with Diego's last known rebellion.
In August 1116 Diego raised the standard of revolt against Alfonso, whose Navarrese lands his lordships bordered.
He was consequently deprived of Nájera, which was bestowed on Fortunio Garcés Caixal, although he may never had actually given it up.
He was allowed to retain Haro and Buradón, which he had received some time after 1110.
In February 1117 Alfonso made a donation to Santa María la Real de Nájera calling himself "Imperator" and still claiming the kingdoms of Urraca.
The donation was confirmed by Diego López, along with Pedro González de Lara and Suero Vermúdez, several bishops and many Aragonese.
The charter is in the style of the Leonese chancery and its authenticity has been called into question, but it may reflect a moment of heightened negotiations between Alfonso and Urraca.
It cannot be taken to reflect a desertion on the part of her major supporters (Diego, Pedro and Suero).
Diego remained on good terms with Alfonso in 1118, when he participated in the "Reconquista" of the great city of Zaragoza, and into 1119, taking part in the continuing conquest of the "taifa".
In July 1124, perhaps encouraged by Urraca or her son, Alfonso VII, Diego again aided by Ladrón of Navarre rose against Alfonso's forces and was besieged in Haro by Alfonso himself.
Alfonso confiscated all his "tenencias" and granted them to Íñigo Vélaz.
There is some discrepancy over when and how Diego died.
According to some source, he died in 1124, probably in the fighting, while others place his death in 1126, after having lost all his lands and titles.
Diego married a certain María Sánchez of obscure origins.
In 1121 he and his wife joined his sister, Toda López, and her daughter, his niece, María López, in making a donation to Santa María la Real.
María Sánchez has been called a sister of García Ordóñez, an impossibility in light of her patronymic; a daughter of Sancho Núñez, son of count Munio Sánchez, ruler of the Duranguesado; and a sister of Lope García Sánchez of the Llodio branch of the Ayala clan.
More likely than any of these hypotheses is that she was a daughter of Sancho Sánchez de Erro, ruler of Tafalla in Navarre, and his wife, Elvira García, daughter of García Ordóñez.
Diego's claim to García's lordships in 1108 may have stemmed partially from his wife's ancestry.
She gave four sons:
Lope Díaz I, who later ruled Biscay and Álava, and three obscure names, Sancho, Fortunio and Gil.
Some historians have reckoned Sancha Díaz de Frias, the founder of , his daughter, but she was more probably a daughter of Diego Sánchez de Ayala and a sister of Toda Díaz.
In May 1140, widowed, María "the mother of Count Lopemater comitis Lupi") and Mayor Garcés gave the monastery of San Ginés to that of San Juan de Burgos.
Diego López IV de Haro
Diego López IV de Haro( died 1289) was a Spanish noble and the Lord of Biscay from 1288 to his death in 1289.
John of Castile, Lord of Valencia de Campos
John of Castile," called the" el de Tarifa( 1262 –25 June 1319) was an" infante" of Castile and León.
He was engaged in a decades long fight for control over the Lordship of Biscay with Diego López V de Haro, the uncle of his wife.
Lope Íñiguez
Lope Íñiguez ("c".
1050 – 1093) succeeded his father Íñigo López to become the second Lord of Biscay in 1076.
Íñigo died shortly after the assassination of his overlord Sancho IV of Navarre and the subsequent takeover of Biscay, Álava, part of Guipúzcoa and La Rioja by Alfonso VI of Castile.
He accepted Alfonso as his lord and his son followed suit, although after Íñigo's death the "tenencia" of Nájera, the most important in La Rioja, which he had held was given to García Ordóñez, husband of Urraca, sister of the deceased Navarrese king.
Nevertheless, it was Lope and Diego Álvarez de Oca whom the king had swear to uphold and guarantee the "fuero" of Nájera which he had granted (1076).
For the loss of Nájera, Lope was compensated with the "tenencias" of Álava (1081) and Guipúzcoa (1082) and he was thus the first to unite the Basque provinces under one lord.
The first record of his simultaneous rule in all three provinces comes from a charter of donation he made to the monastery of San Millán de la Cogolla in 1082, which he signed as "I, lord Lope Íñiguez, governing Biscay, Guipúzcoa and Álava".
This concentration of political authority led to the suppression of the Diocese of Álava and the consignment of its province to the Diocese of Calahorra in 1087.
In 1089 Lope received the title of count, the highest rank in the kingdom, from Alfonso.
Lope's importance continued to grow, for in 1091, at his instigation, Alfonso VI donated the monastery of San Andrés de Astigarribia, which lay on the border between Biscay and Guipúzcoa, to San Millán.
Lope was a regular participant in Alfonso VI's "Reconquista".
He probably took part in the conquest of Toledo in 1085.
Forces from Álava are known to have participated in the Battle of Sagrajas in 1086, probably under his leadership.
In the spring of 1092 he probably joined with García Ordóñez in defending the Rioja from the depredations of the exile and freebooter Rodrigo Díaz de Vivar.
Lope married
Ticlo (Tecla) Díaz, daughter of a certain Diego Álvarez, possibly Diego Álvarez de Ayala, who ruled Asturias de Santillana, but more probably Diego Álvarez de Oca.
Their marriage took place before 1079, when the couple made a donation to San Millán.
Ticlo may have brought part of Las Encartaciones to Lope, thus uniting them permanently with Biscay.
She gave birth to an heir, Diego I, named after her father.
The names Diego and Lope would alternate in the heads of the family for generations.
Ticlo bore four other children:
Sancho, Toda (who married Lope González, who succeeded Lope in Álava), Sancha and Teresa (who married García Sánchez de Zurbano and later went on a pilgrimage to Rome).
Shortly after Lope's death in 1093
Ticlo donated the monastery of Albóniga to San Millán for the good of his soul.
She died towards 1104 and was buried in San Millán.
Lope may also have been the father of Pedro López de Monforte.

Lope Díaz II de Haro Cabeza Brava( b. 1170 – d. 15 November 1236) was a Spanish noble of the House of Haro, the sixth Lord of Biscay, and founder of the municipality of Plentzia.
He was the eldest son of Diego López II de Haro and his wife, María Manrique.
Lope was also a member of the Order of Santiago.
Teresa Díaz II de Haro
Teresa Díaz II de Haro( born before 1254) was a Spanish noble woman and a lady of Biscay, and one of five children of Diego López III de Haro, the Lord of Biscay, and Constanza de Bearne.
