A focused population profile of Carloforte Ligurians, their western Mediterranean island background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Carloforte Ligurians are a Ligurian-speaking island community on San Pietro Island off southwestern Sardinia. Their history is tied to Ligurian settlers from Pegli, the Tabarka community off Tunisia, Mediterranean migration, and the foundation of Carloforte in the 18th century.
Italian is the national language, while Tabarchino is a Ligurian variety that remains central to local identity. Carloforte should be read as a specific Ligurian island reference, not as a broad Sardinian or mainland Ligurian average.
As a genetic reference, Italian Carloforte Ligurian is useful for comparison with Corsican, Lombardy Brescia, Piedmont Val Borbera Ligurian, Emilian, Lombard, Tuscan, Bergamo Lombard, Romagnol, Swiss Italian, and Venetian references.
In the World Genetics modern G25 comparison, the closest non-self match for Italian Carloforte (Ligurian) is Corsican. Other nearby references include Italian Lombardy Brescia (Lombard), Italian Tuscany (Tuscan), Italian Piedmont Val Borbera (Ligurian), and Italian Emilia (Emilian). This gives the Italian Carloforte (Ligurian) profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Carloforte Ligurian is best interpreted as a Ligurian-derived western Mediterranean island profile, close to Corsican and several northern/central Italian references.
The heatmap should emphasize Carloforte, San Pietro Island, Ligurian-related regions, Corsica, Lombardy, Val Borbera, Emilia, Tuscany, Romagna, and the western Mediterranean.
The closest non-self match in this World Genetics comparison is Corsican. Other nearby references include Italian Lombardy Brescia (Lombard), Italian Tuscany (Tuscan), Italian Piedmont Val Borbera (Ligurian), and Italian Emilia (Emilian).
In the current modern G25 reference set, Corsican is the closest listed match to the Italian Carloforte (Ligurian) average after removing Italian Carloforte (Ligurian) itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Italian Carloforte (Ligurian) G25 average, giving the closest-match results a geographic view.
