Casa de Zúñiga-Biedma
Marriage and inheritance joined the Biedma, Ulloa and Zúñiga interests. Follow the house of Monterrey from its Galician estates to the royal court.

Why this matters hereZúñiga–Biedma · Inherited power
Marriage and inheritance joined the Biedma, Ulloa and Zúñiga interests in the house of Monterrey. This is a story of estates and offices extending beyond the Ribeiro into the Limia and royal court. Claims about a particular shield in Cartelle need a dated inscription or local record before they can establish ownership or descent.
The Arms
Two shields, one house
Zúñiga: Argent, a bend sable; in orle brochant over all, a chain of eight links or.

Biedma: an illustrated variant with a red pale and eight black cauldrons on gold. The Salamanca monument places the cauldrons on a silver border.
Frontier Men: From Castile to the Southern Marches of Galicia

The Biedma reached Galicia through royal service around the turn of the fourteenth century. Fernán Rodríguez de Biedma, also called Fernán Ruiz in lineage accounts, accompanied the Infante Felipe as his ayo, or tutor and guardian. Felipe was a son of Sancho IV and María de Molina, not the king’s brother. His household helped consolidate royal authority in Galicia during an unsettled succession.
Fernán and Marina Páez de Soutomaior appear together in scholarship on Sancho IV’s court. Their son Ruy Páez became adelantado de Galicia and cupbearer to the Infante Pedro. His testament of 1342 is a particularly revealing document: he requested burial at Santa Clara de Allariz, beside but lower than Felipe’s tomb. Service, landed rights and religious patronage together explain the family’s growing position around Allariz, Monterrei and A Limia.
The same testament brings the house directly into the Ribeiro: Ruy Páez left 1,000 maravedís and his share in Trasariz and Sanín for work on Santa Clara. These named properties show how the fortunes of a court household reached into the Miño and Avia country. Allariz and Monterrei were separate centres, linked to the Ribeiro through holdings and patronage rather than belonging to the same comarca.
- Fernán Rodríguez / Ruiz de Biedma: royal servant and tutor of the Infante Felipe.
- Felipe: son of Sancho IV and María de Molina.
- Ruy Páez de Biedma: adelantado and cupbearer; testament of 1342.
- Santa Clara de Allariz: burial and patronage connect household and monastery.
Salado, Montiel, and the Opposite Side of Loyalty

The careers of the Biedma and Castro houses crossed in royal service before the civil war placed their leading representatives on opposing sides. Juan Rodríguez de Biedma served Pedro I as cupbearer, but later supported Enrique de Trastámara. Lineage accounts connect the change with the execution of his son Rodrigo Yáñez. The family’s position must be read within a conflict whose allegiances could change.
Grants recorded for 1368–1369 enlarged the Biedma lordship across southern Ourense: Loveira, Entrimo and Araúxo; Vilanova dos Infantes, Castrelo and Espinoso; and places in A Limia and the Laza valley. The 1369 grant associated with Braganza is part of this sequence. The precise boundaries and rights in each place depend on the individual charter, rather than on a modern map of one homogeneous frontier state.
These rewards help explain the later Monterrei inheritance and the family’s local presence near Cartelle. They formed part of Enrique II’s wider redistribution of authority after Montiel. The Castro and Sarmiento pages follow the other side of that change; the Biedma story shows how another royal household gained a lasting territorial base.
- Juan Rodríguez de Biedma: royal officer who supported Enrique II.
- 1368–1369: a sequence of grants across southern Ourense.
- Espinoso: a local connection to the parish in Cartelle.
- Each charter distinguishes property, rents and jurisdiction.
A Navarrese Name and a Galician Inheritance

Zúñiga, also written Stúñiga in medieval records, takes its name from a Navarrese locality. Later genealogies claimed descent from Íñigo Arista, the first king of Pamplona; that prestigious origin should be distinguished from a complete documented pedigree. The family’s rise in Castilian service followed its movement out of Navarre during the late-thirteenth-century political conflicts.
Diego López de Stúñiga el Viejo became Justicia Mayor of Castile. PARES identifies Diego el Mozo as his son, not his grandson. The younger Diego’s marriage to Elvira de Biedma joined patrimonies in Galicia, and royal grants further strengthened their position around Monterrei. Marriage and royal favour worked together; the estate was not acquired in one uninterrupted act.
Later inheritances and disputes carried the combined Zúñiga-Biedma name into the Monterrei titles. This helps explain the arms and patronage found in southern Ourense. It does not attach everyone bearing either surname to this noble branch, nor establish a link to our family without the intervening records.
- Zúñiga / Stúñiga: a Navarrese place name.
- Descent from Íñigo Arista: a lineage tradition.
- Diego el Mozo: son of Diego el Viejo, according to the PARES authority record.
- Marriage to Elvira de Biedma: an important Galician inheritance.
The County of Monterrey: From Galicia to the Americas

The descendants of Diego and Elvira inherited property through settlements as well as lawsuits. The viscounty of Monterrei and the later county were stages in a complicated succession involving Zúñiga, Biedma and Ulloa. Sancho Sánchez de Ulloa became the first Count of Monterrei in 1474, married to Teresa de Zúñiga y Biedma. Distinguish this Teresa from the Countess of Santa Marta killed at Ribadavia in 1470.
Monterrei lies above the Támega valley near Verín, east of the Ribeiro. Its buildings record successive generations of patronage: Sancho Sánchez de Ulloa commissioned the late-fifteenth-century keep, while the Counts’ Palace took shape in the sixteenth and seventeenth centuries. The Jesuit college was founded in 1555–1556 and became a centre of education serving a much wider region. These structures show how a military seat also developed as a noble residence and place of learning.
Gaspar de Zúñiga y Acevedo, fifth count of Monterrey (1560–1606), carried the family’s court service to the Americas as viceroy of New Spain and later Peru. His licence to sail in 1595 survives at the Archivo General de Indias. Diego de Montemayor named Monterrey in Mexico for the viceroy in 1596. Sebastián Vizcaíno gave Monterey Bay in California the same name in 1602 while surveying a possible harbour for the Manila galleons. The name travelled through imperial administration and exploration, into lands with their own established communities and histories.
- Vizcondado de Monterrey: granted by Juan II of Castile to Juan de Zúñiga y Biedma
- Condado de Monterrey (1474): granted to Sancho Sánchez de Ulloa, married to Teresa de Zúñiga y Biedma
- Pertiguería Mayor de Santiago: the military governorship of the lands of Compostela — held by the Castros in the 13th–14th century, inherited by the Monterrey counts
- Gaspar de Zúñiga y Acevedo (1560–1606): V conde de Monterrey, viceroy of New Spain (1595–1603) and Peru (1604–1606); the city of Monterrey, Mexico (founded 1596) and Monterey Bay, California (named 1602) bear his title
Espinoso: Parish Patronage in Cartelle

San Miguel de Espiñoso, in Cartelle, gives this history a local architectural anchor. The municipal heritage inventory dates the Baroque church to 1749, with enlargement in 1780. Its façade carries the arms of Zúñiga and Biedma; inside are a star-ribbed vault and a neoclassical main altarpiece. Cartelle belongs to Terra de Celanova, adjoining the wider Ribeiro landscape.
Espinoso also appears in accounts of the Biedma grants of 1369. To trace the connection across centuries, the carving should be read with patronage records, estate documents and Pedro González de Ulloa’s 1777 description of the Monterrei states. Arms alone do not establish who paid each rent or which court heard every dispute.
The parish name and the surname Espinosa share a word relating to thorny ground, but that resemblance is not a genealogical link. What matters for this guide is the visible presence of noble patronage within the Terra de Celanova, alongside monasteries, municipal communities and the Hospital of St John.
- San Miguel de Espiñoso: parish of Cartelle.
- Baroque church with arms associated with Zúñiga-Biedma.
- 1777: González de Ulloa’s description offers context for the Monterrei estate.
- The resemblance to the surname Espinosa does not establish ancestry.
A Black Band, a Gold Chain, and Eight Calderas
Joaquín Alemany Giner’s study of the arms at Liria and the Agustinas church in Salamanca describes the Zúñiga device as a black bend on silver with a gold chain of eight links. For Biedma, the Salamanca example has a red pale on gold and a silver border carrying eight black cauldrons: three on each flank, one above and one below. Borders and arrangements vary between monuments.
The same study repeats older stories connecting the chain with Las Navas de Tolosa and the change of colours with mourning for crusading rulers. These are inherited explanations of the arms. They should be distinguished from the dated monuments that preserve the devices and from contemporary documents establishing who used them.
- Zúñiga: silver field, black bend and gold chain of eight links.
- Biedma at Salamanca: gold field, red pale and silver border with eight black cauldrons.
- The illustrated Biedma arrangement differs from the Salamanca monument.
- Origin stories explain lineage traditions; they do not date a particular surviving shield.
