Geographic Frequencies in Ashkenazi Y-DNA Haplogroup I
This page sets forth information compiled using FTDNA's Discover Tool concerning the most distant known direct male ancestor reported by each of the Big Y-tested men in any of the Ashkenazi Y-DNA clusters in haplogroup I identified through the analysis described elsewhere on this website. The information was compiled on April 22, 2023 by using the Discover Tool's Country Frequency page (in Table View) for each of the three Y-DNA clusters in haplogroup I identified through the refined analysis performed on this website in December 2022.
This page posts, by size and in alphabetical order, charts of each country identified as an ancestral country by one or more of the men in each cluster, followed by the percentage of men (total number of men) with reported ancestry in each country.
