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 table, Italian Carloforte Ligurian is closest to Corsican, Italian Lombardy Brescia Lombard, Italian Piedmont Val Borbera Ligurian, Italian Emilia Emilian, Italian Lombardy Lombard, Italian Tuscany Tuscan, Italian Lombardy Bergamo Lombard, Italian Romagna Romagnol, Swiss Italian, and Italian Veneto Venetian. The result places Carloforte in a Ligurian/western Mediterranean and north-central Italian-related space.

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.
Carloforte is located in Sardinia, but this reference is Ligurian-derived and appears closest to Corsican and north-central Italian references.
Corsican is the closest match in this table, reflecting western Mediterranean island and Ligurian-adjacent similarity.
Val Borbera Ligurian appears among the closest matches, giving a mainland Ligurian/Piedmont border comparison point.
