Your paternal lineage may be linked to early Balkan migrants

Haplogroup E1b1b1a1b1a migrated in large numbers from the Balkans into Europe about 4,500 years ago, triggered by the beginning of the Balkan Bronze Age. During this migration, members of haplogroup E1b1b1a1b1a mainly followed rivers connecting the southern Balkans to northern-central Europe. Technological leaps often cause lineages to grow dramatically in numbers and in geographic range. The development of Bronze technology may have given men in haplogroup E1b1b1a1b1a a competitive advantage over other men, causing haplogroup E1b1b1a1b1a to proliferate and become widespread.

Your maternal lineage may be linked to some of the first Americans

Though the Ice Age was beginning to retreat when your A2 ancestors first entered North America, there were still massive barriers blocking their way. Glaciers and inhospitable climate covered much of the continent, blocking entry into the interior. Nonetheless, researchers have found evidence that a wave of American founders migrated over 13,000 kilometers to reach southern Chile in only 2,000 years, a blink of an eye in the story of human migration! Their highway to the south was the coast of the Pacific, stocked with fish, diverse marine mammals, and other valuable resources in the rich kelp forests of the upper latitudes and in the abundant fresh-water rivers near the equator. Because of this rapid movement south, the A2 haplogroup and its diverse branches are found throughout North and South America.
