In a newly posted video, Bennett Greenspan, founder of FamilyTreeDNA, breaks down how modern Y-DNA testing can help genealogists explore the direct paternal line, compare Y-DNA matches, investigate surname lines, and push past genealogy brick walls when traditional records reach their limits.
Using the story of his own family research, Bennett shows how Y-DNA results, STR markers, SNPs, haplogroups, terminal SNPs, and Big Y matching helped him identify paternal-line connections, trace migration patterns, and connect branches of a family tree across centuries, even a millennium and more.
