Figure S1. Geographic distribution of Y-chromosome main lineages in the studied
populations. Only haplogroups reaching frequencies of at least 3% in the combined dataset were
plotted. Color code for Y-chromosome lineages as in the legend at the top right. Labels:
ARB_CAL: Arbereshe of Calabria, ARB_SIC: Arbereshe of Sicily; SSI: Sicilians and SouthernItalians, ALB: Albanians, GRE: Greeks. Haplogroup composition for each community of
Calabrian and Sicilian Arbereshe are detailed in the boxes at the top- and bottom-left of the plot
respectively (Codes for single Arbereshe communities as in Table S1).
Figure S2. Non-metric MDS plot based on STRs distances. Population codes as in Table S1.

Figure S3. Phylogenetic haplotypes network of haplogroup E-V13. Each circle represents a
different haplotype. Circles’ areas are proportional to haplotype frequencies. White circles
represent median vectors. Population color codes as in the legend. Abbreviations: ARB_CAL:
Arbereshe of Calabria, ARB_SIC: Arbereshe of Sicily; ITA: Sicilians and Southern-Italians,
ALB: Albanians, GRE: Greeks. Red oval designates the Calabrian Arbereshe-specific cluster (EV13α) selected for age estimate.
Figure S4. Phylogenetic haplotypes network of haplogroup I-P215(xM26,M223). Each circle
represents a different haplotype. Circles’ areas are proportional to haplotype frequencies. White
circles represent median vectors. Population color codes as in the legend. Abbreviations:
ARB_CAL: Arbereshe of Calabria, ARB_SIC: Arbereshe of Sicily; ITA: Sicilians and SouthernItalians, ALB: Albanians, GRE: Greeks. Orange oval designates the Sicilian Arbereshe-specific
cluster (I-P215α) selected for age estimate.
Figure S5. Phylogenetic haplotypes network of haplogroup R-SRY10831.2. Each circle
represents a different haplotype. Circles’ areas are proportional to haplotype frequencies. White
circles represent median vectors. Population color codes as in the legend. Abbreviations:
ARB_CAL: Arbereshe of Calabria, ARB_SIC: Arbereshe of Sicily; ITA: Sicilians and SouthernItalians,
ALB:

the
shared
Calabrian/Sicilian Arbereshe-specific cluster selected for age estimate.
Figure S6. Phylogenetic haplotypes network of haplogroup I-M223. Each circle represents a
different haplotype. Circles’ areas are proportional to haplotype frequencies. White circles
represent median vectors. Population color codes as in the legend. Abbreviations: ARB_CAL:
Arbereshe of Calabria, ARB_SIC: Arbereshe of Sicily; ITA: Sicilians and Southern-Italians,
ALB: Albanians, GRE: Greeks. Red oval designates the Calabrian Arbereshe-specific cluster (IM223α) selected for age estimate.
Figure S7. Phylogenetic haplotypes network of haplogroup E-M123. Each circle represents a
different haplotype. Circles’ areas are proportional to haplotype frequencies. White circles
represent median vectors. Population color codes as in the legend. Abbreviations: ARB_CAL:
Arbereshe of Calabria, ARB_SIC: Arbereshe of Sicily; ITA: Sicilians and Southern-Italians,
ALB: Albanians, GRE: Greeks. Red and orange ovals designate the Calabrian (E-M123α) and
Sicilian (E-M123β) Arbereshe-specific clusters respectively, which have been selected for age
estimates.
