Yes Virginia, Old World Europeans do still exist.
A daughter of Clan Ursula (also known as Clan Europa), my ancestral genetic U5b1b1-T16192C! motherline is a founding maternal lineage of Old World Europe, the Atlantic North Sea regions of Europe and Arctic Fennoscandia. Myself being 80% ethnically of the British Isles by autosomal genetic anaylsis, my own U5b1 genetic motherline has specifically been found in samples of ancient DNA from the people of the old world Atlantic Megalithic Culture (7000 to 4000 ybp) - the culture which existed on the islands in ancient times and is thought to have built Stonehenge, Newgrange, Castlerigg Stone Circle and other megalithic sites of the sacred landscape. The U5 ancestral clade is the oldest extant indigenous European motherline among modern humans and the dominant maternal lineage among Paleolithic and Mesolithic European hunter-gatherers.
A daughter of Clan Woden (the only pre-Neolithic Y-lineage left in Europe), my paternal ancestral I2 (I-M223, on subbranch I-Z166, subbranch I-S20905, subbranch I-Y20888) genetic fatherline is also indigenous to Europe (arising in Ice Age Doggerland which became submerged under the North Sea) and is a Northern-Northwestern Germanic Anglo-Saxon-Frisian-Jute-Danish-Norman, Southern Sweden Old World European fatherline.
In Paleolithic Europe, my ancestral genetic mtDNA motherline group has been found in samples of ancient human DNA from people in these cultures: Eastern European Proto-Aurignacian (47,000 to 43,000 ybp), Aurignacian (43,000 to 28.000 ybp, in all areas of ice-free Europe, including the areas renowned for Ice Age Cave Art), Gravettian (31,000 to 24,000 ybp, also in all areas of ice-free Europe), Solutrean (22,000 to 17,000 ybp in France and Spain), Magdalenian (17,000 to 12,000 ybp in Western Europe), in Epipaleolithic France (13,000 to 10,000 ybp), Epipaleolithic Germany (13,000 to 11,000 ybp) and in the Azilian Culture (12,000 to 9000 ybp in Western Europe).
In Mesolithic Europe (20,000 to 9500 ybp), my ancestral genetic motherline group has been found in samples of ancient human DNA from people inhabiting ancient Germany, Spain and Sweden (Pitted Ware Culture).
In Neolithic and Chalcolithic Europe, my ancestral genetic motherline group has been found in samples of ancient human DNA in people from the Atlantic Megalithic Culture (9000 to 4000 ybp), Neolithic Alsace of Eastern France (7500 to 6300 ybp) and Neolithic Britain (6000 to 4000 ybp).
In Paleolithic Europe, my bloodline ancestral genetic Y-DNA fatherline group has been found in samples of ancient human DNA from people in these cultures: Eastern European Proto-Aurignacian, ice-free Europe Aurignacian, Western European Magdalenian, Epipaleolithic France and Western European Azilian.
In Mesolithic Europe, my bloodline ancestral genetic fatherline group has been found in samples of ancient human DNA from people inhabiting ancient France, Germany and Sweden.
In Neolithic and Chalcolithic Europe, my bloodline ancestral genetic Y-DNA fatherline group has been found in ancient human DNA samples from people from the Western European Atlantic Megalithic Culture, the Northern European Funnel Beaker Culture (aka TRB, 6000 to 4700 ybp), and the Baalberge (5800 5350 ybp) and Salzmunde (5400 to 5000 ybp) groups of Germany.
Between 11,500 and 9300 ybp, both my ancestral genetic motherline and fatherline groups inhabited Greater Doggerland, also known as the North Sea Atlantis.
My own autosomal DNA tests have proven that my overall genetic ancestry is 45% from Paleolithic Old World European hunter-gatherer groups and 100% ethnically European since at least the Neolithic. So, not only are my genetic ancestral motherline and fatherline rooted in Paleolithic Old World Europe, but my overall genetic ancestry is also in large portion from Paleolithic Old World Europe.
Taking the data together, my bloodline genetic mothers, genetic fathers, and a large percentage of my ancestors have inhabited Europe for nearly 50,000 years!
