DNA analysis is the latest genealogy research tool through which family relationships can be determined. By combining traditional genealogy and genetics, common ancestors can be identified. DNA is used because of its unique nature and the fact that it is passed down from one generation to the next. In the passing, some parts of the DNA such as the Y-chromosome, remain almost completely unchanged. This property allows for the identification of certain consistencies between individuals who have a common ancestor. Male Y-chromosome testing identifies common ancestors with the same surname.
For Balbi descendants today this is an exciting opportunity that goes beyond traditional genealogy research methods to link Balbi family branches throughout the world. Toward this goal a Balbi surname DNA project has been established for Balbi descendants. Because the Y-chromosome is carried by males, the DNA test can only be taken by a male whose surname is Balbi. However, results of his test would reveal his Balbi DNA, his Balbi ancestors' and all Balbis, male and female, who are related to him.
A comparison of Balbi DNA participants can be viewed at the DNA Results page. To view the Balbi DNA Project at Family Tree DNA: Go to the Family Tree DNA home page (www.familytreedna.com); click on Projects at the top of the page; in Project Search, equals, type in balbi; under Projects click on Balbi; click on the Project Website; at the YDNA Results tab, click on Colorized and the Balbi DNA project will be displayed. The colored boxes reflect DNA marker differences among participants. If you are a male whose surname is Balbi, Balbis, Balby, Balbus or any other derivative and have an interest in participating, please contact Cindy Balbi Oliver at firstname.lastname@example.org.

Haplogroup: Haplogroups are branches of the Y-chromosome genetic tree. Haplogroup comparisons are used to bring together genetic cousins, explore family genealogical roots, and plot the migration of various branches of a given surname. With its roots in Africa approximately 140,000 years ago, as time passed, small mutations occurred in the Y-chromosome. Whenever a mutation happened the tree branched out and over time as people migrated into different continents and regions, a tree-like structure was created with branches found in certain parts of the world.
Haplogroup E is split into E1, E2 and E3. E1 and E2 have been observed almost exclusively on the African continent. The third branch, E3, is seen within Africa, Europe and western Asia. As it is the only haplogroup to be seen both inside and outside of Africa, it is evidence of the "out-of-Africa" theory where a likely small group of modern humans within Haplogroup E3 crossed from Africa into the Near East approximately 75-80,000 years ago. Early research held the theory that E3b was spread by the expansion of farmers though the Neolithic period (6000-2900 BCE), however further studies reveal a more complex picture of migration events beginning approximately 25,000 years ago in East Africa.
Haplogroup G is considered to be about 14,300 years old. It is observed in high frequency and diversity in Georgia within and south of the Caucasus Mountains which would suggest an origin. This haplogroup also has a strong linguistic affiliation to the northwest Caucasian languages, with their paucity of phonemic vowels and rich consonantal sounds. Additionally high frequencies north of the Caucasus in North Ossetia are detected, although as there is less haplotype diversity in this northern region it would suggest that only a few founding lineages entered and became successful over time. Upper Paleolithic inhabitants of Weasel Cave in North Ossetia may well have fallen into this haplogroup. This haplogroup is also seen south into Iraq and into Southeastern Europe but almost entirely absent from the rest of Europe.
Haplogroup 12 is seen about 22,000 - 23,000 years ago and possibly stemmed from descendants who arrived from the Near East about 25,000 years ago. As the last ice age began it became necessary to move down to below the tree line to hunt game. At its peak, the ice shelf within Europe extended down as far as southern Ireland, the middle of England and across northern Germany. Scandinavia was entirely covered. The sea-ice pack extended as far as northern Spain and tundra covered much of continental Europe. The tree line at the height of the ice age was as far south as Southern France, Northern Italy, north of the Balkans and across the Baltic Sea. Haplogroup I populations predominately took refuge in the Balkans.
Haplogroup R1b members are believed to be the descendants of the first modern humans who entered Europe about 35,000-40,000 years ago. Those R1b forebearers were the people who painted the beautiful art in the caves in Spain and France. They were the contemporaries, and perhaps exterminators, of the European Neanderthals. R1b is the most common Y haplogroup in Europe; more than half of men of European descent belong to R1b.
Y Chromosome: The Y-chromosome is the most widely used application of genetics in genealogy. Passed from father to son, the Y-chromosome remains virtually unchanged from generation to generation. Therefore, examining the Y-chromosome of a living male representative on a given paternal line will reveal information about each of the preceding male ancestors (living or deceased) in that same line and allow for the identification of shared ancestry or verification of existing genealogies.
DNA Marker Match: Refers to the number of Y-chromosome marker matches there are among participants.
43/43 is a perfect match that indicates that there is a shared direct paternal line ancestry within a small number of generations, probably 3.
42/43 indicates that there is a shared paternal line ancestry statistically in fewer than 8 generations with the most likely estimate for a common ancestor 4 generations ago.
41/43 indicates that there is a shared direct paternal line ancestry, statistically in fewer than 13 generations, with the most likely estimate for a common ancestor 9 generations ago.
40/43 indicates presumed shared direct paternal line ancestry and if so, a shared direct paternal line ancestry in fewer than 17 generations, with the most likely estimate for a common ancestor 13 generations ago.
39/43 indicates that it is unlikely that there is a shared direct paternal ancestry in fewer than 20 generations.
26/26 is a perfect match that indicates that there is a shared direct paternal line ancestry within a small number of generations, probably 5.
25/26 indicates that there is a shared paternal line ancestry statistically in fewer than 13 generations, with the most likely estimate for a common ancestor 7 generations ago.
24/26 indicates that the two men presumably share direct paternal line ancestry in fewer than 20 generations, with the most likely estimate for a common ancestor 14 generations ago.
23/26 indicates that it is unlikely that there is a shared direct paternal ancestry in fewer than 28 generations, with the most likely estimate for a common ancestor 22 generations ago.
