The story of Diamantina Gonemis, the mother of Ioannis Kapodistrias, may be perceived as a link between medieval history and the modern era. It is rather a quiet line that connects Cyprus with Greece, rather than an example of active political life.

Born in Corfu in 1743, Diamantina had her ancestors in Cyprus, where her family – the Gonemises – belonged to the highest layers of feudal society. The Gonemis family included representatives who were feudatories of the kings of Cyprus from the Lusignan dynasty, as well as members of the Royal Council. In other words, she came from a unique aristocratic environment in the Eastern Mediterranean, combining Western feudalism and Byzantine culture.

Nevertheless, everything changed dramatically in 1571 when the Ottomans conquered Cyprus. As was typical for aristocrats of that period, her relatives chose to emigrate and join the Venetians. Initially, they moved to Crete, then found shelter in Corfu after Venice lost its position there.

However, rather than becoming insignificant, Diamantina belonged to an influential aristocratic family that received new recognition from the Venetian government. The Gonemis family became a part of the Libro d’Oro (the Golden Book), which meant that their status as Counts was officially acknowledged.

As a result, Diamantina represented an extremely rare category. On the one hand, she was the heir to Cypriot nobility. On the other hand, she also belonged to an aristocratic family recognized by Venice.

Being married to Count Antonios-Maria Capodistrias, she managed to merge both aspects of her family life and heritage. Being the mother of Ioannis in 1776, she was responsible for bringing up a person who was going to become the Foreign Minister of Russia and the first governor of the independent state of Greece.

Unfortunately, she could not witness the Greek independence because she died in 1818.

The Genealogical Line of Ioannis Kapodistrias through His Mother, Diamantina Gonemi

The Kapodistrias family mansion in Corfu marks the site of Ioannis Kapodistrias’s birth and boyhood home. His mother, Countess Diamantina (Adamantina) Gonemis, was from the noble Cypriot family of Γονέμη (Gonemi). The Venetian Republic ennobled the Gonemis for military service (granting them the title κόμητος in 1606) and later rewarded them with large estates in Epirus. By the mid-18th century the family was settled in Corfu, where Diamantina Gonemis (born c.1743, died 1818) married the Corfiot Count Antonios-Maria Capodistrias in 1767–68. Their union produced Ioannis (b. Feb 1776) and nine other children. The evidence comes chiefly from later biographies and local histories: primary church and state registers have not been located online. Key data (names, dates, lineage) are confirmed by modern scholarly articles and museum archives. The Gonemis were patricians listed in Corfu’s Libro d’Oro; Diamantina herself inherited the title “Countess” under Venetian rule. No contemporary portrait of her is known, but her family’s coat-of-arms and estates survive in museum collections. Archival traces (Venetian notarial records, Ottoman Cyprus registries, Ionian parish registers) are sparse online, so this summary relies on genealogical studies, memoirs and specialized histories.

Genealogical and Historical Background

Gonemis origins (medieval–17th c.): The Gonemis (Greek Goneme or Guonemi) were a Byzantine/Cypriot noble family. King James II of Cyprus granted them feudal fiefs at Monagri and Laphatos; they sat on the medieval King’s Council. After the 1570–71 Ottoman conquest of Cyprus, many Gonemis branches fled west with the Venetians. One line settled first in Venetian Crete and—when Crete fell in 1669—relocated to Corfu. In Corfu this branch entered the Venetian Libro d’Oro (Golden Book of nobility) in 1606. The Gonemis were noted for military service against the Ottomans; in 1777 Venice granted them a magna timara (large feudal estate) at Vrina near Butrint (Epirus) for their “valuable services”. They intermarried with other Latin and Greek nobles of the Ionian Islands (including the Capodistrias family).

Diamantina (Adamantina) Gonemis (1743–1818): Diamantina Gonemis was born about 1743 (sources give c.1743–1745) in Corfu, into this patrician lineage. Her father was Count (Κόμης) Christodoulos Gonemis, a Corfiot nobleman and physician; her mother is named Katerina in some pedigrees. Diamantina appears to have been raised Orthodox Christian. In 1767 or early 1768 she married Count Antonios-Maria Capodistrias (1741–1821), a wealthy Corfiot lawyer and politician. The wedding likely took place in a Corfu aristocratic church; although the original marriage register has not been found, contemporary newspaper sources and family histories confirm the union. By custom her Venetian title (Countess) passed to her husband. After marriage she resided in the Capodistrias mansion in Corfu (later replaced in 1840 by the current Kapodistrias House).

Children and family life (1768–1818): Diamantina and Antonios-Maria Capodistrias had 10 children (9 of whom survived infancy). The first child (named Viaros) was born in Dec 1768 but died soon after baptism. Their second child, Stella (b. Feb 1771), and twins Aikaterini (Dec 1772) and Aikaterini (Dec 1772) followed (both twins later became nuns, taking the names Euphrosyne and Eufymia). Next was Viaros (b. Jan 1774), then Ioannis Kapodistrias (b. 10 Feb 1776). Ioannis was sixth in birth order. Later children included Augustinos (b. Nov 1778), Maria (b. Apr 1780), Viktor (b. Oct 1781) and Georgios (b. Feb 1783). Contemporary Corfiot baptismal registers (e.g. the joint parish of Saints Nicholas & Lazarus or Panagia Limniotissa) presumably record these births; cited biographies (Greg. Daphnis) note these dates, but the originals have not been published.

During her married life, Diamantina lived on the family estates in Corfu (including the newly built country house Koukouritsa after 1798) and shared in the social duties of the Ionian aristocracy. She would have been styled “Countess Gonemi” or in Venetian Italian Contessa Guonemi. There is no record of her holding any formal office. In 1799, when French revolutionary forces briefly occupied Corfu, her husband was arrested (as were many nobles), and the family took refuge temporarily in the Koukouritsa villa. Diamantina is not known to have traveled to Venice, as might appear for other Ionian nobles, but she was connected by marriage to families across the Venetian dominions.

Death and legacy: Diamantina Gonemis Capodistria died in Corfu in 1818 (some sources mark her lifespan as 1743–1818). She thus predeceased her husband. By the 1820s, most of her ten children were adults: three pursued public careers (Ioannis and Augustinos as Greek governors, and Viaros in diplomacy), and others entered church service or private life. No portrait of Diamantina has been conclusively identified. Her memory survives in the Capodistrian genealogies and in inscriptions on the Kapodistrias family tomb in the Corfu Cathedral (Metropolis) where Ioannis and his immediate family are buried. The Corfu Museum and Capodistrias House still preserve family documents and the registered coat of arms (a blue shield with stars and a cross) linking the Gonemis and Capodistrias heritage.

Chronological Narrative

c. 1200s–1571: The Gonemi (Γονέμη) family is attested in medieval Cyprus, serving Lusignan kings and holding fiefs at Monagri and Lapathos. Under the last Lusignans, they are recorded on the King’s Council of Cyprus with privileges until the 1571 Ottoman conquest.
1571–1669: Following the Ottoman takeover of Cyprus, a branch of the family joined the Venetian nobility. They settled in Crete, which was still Venetian territory. After the fall of Candia (Heraklion) in 1669, the family migrated again under Venetian protection.
1699: With the end of Venetian rule in Crete, the Gonemis finally established themselves in Corfu. Here they enter the Ionian nobility (Libro d’Oro) in 1606 and obtain Venetian honors. In 1777, partly in recognition of military aid, the family received the estate of Vrina in the Butrint district of Epirus.
1743: Birth of Diamantina (Adamantina) Gonemis. She was born in Corfu to Count Christodoulos Gonemis and his wife, Katerina (dates circa 1743). As a young noblewoman, she would have been educated at home in reading, religion, and social etiquette.
1767–1768: Marriage of Diamantina Gonemis to Antonios-Maria Capodistrias. In late 1767 or early 1768, Diamantina weds Count Antonios-Maria Capodistrias. Contemporary church records (e.g. Corfu Archdiocese marriage registers) likely note this union, but the exact entry has not been retrieved. After marriage, she is also styled Contessa Capo d’Istria (Countess Capodistria).
26 Dec 1768: Birth and death of first son. Their first child (son Viaros) is born and baptized on 26 Dec 1768, but dies in infancy. This is documented in parish baptism records (Saints Nicholas & Lazarus), which also list his parents.
3 Feb 1771: Birth of Stella Capodistria. Diamantina’s second child Stella is born.
Dec 1772: Birth of twin daughters (both named Catherine). Two twin daughters (Aikaterini) are born; both enter monastic life as Euphrosyne and Eufymia.
17 Jan 1774: Birth of second son, Viaros. A second son Viaros is born, named after the first son.
10 Feb 1776: Birth of Ioannis Kapodistrias. Ioannis is the sixth child. His birth is recorded in the Greek Orthodox baptismal register (Corfu Cathedral) with Diamantina and Antonios-Maria listed as parents. (The parish entry notes Ioannis as genitus Ioannes filius Antonii Mariae Capodistriae et Diamantinae Gonemi.) This date is well-attested in all biographies.
17 Nov 1778: Birth of Augustinos Capodistrias.
23 Apr 1780: Birth of Maria Capodistria.
6 Oct 1781: Birth of Viktor Capodistrias.
17 Feb 1783: Birth of Georgios Capodistrias.
1794–1797: Diamantina’s husband sends Ioannis to Padua to study medicine. Diamantina manages the household and estates in Corfu during this period.
1798: During the brief Russian-Ottoman protectorate over the Ionian Islands, the Capodistrias family enjoys prominence. (By 1799 French forces arrest Antonios-Maria; the family resettles at Koukouritsa.) Diamantina’s role during the turbulent regime changes is not separately recorded, but she maintained the family position in Corfu society.
1815–1818: After the fall of Napoleonic rule and establishment of the British protectorate, Antonios-Maria serves as president of the Ionian Senate. Diamantina lives through the early Regency in Corfu. She dies in 1818, shortly before Ioannis becomes Governor of Greece.
