Your paternal lineage may be linked to the people of Doggerland
One of the places that was repopulated as the Ice Age waned no longer exists. During the Ice Age and for some time afterward, lower sea levels exposed much of the area that is now covered by the North Sea. Known as "Doggerland," the region must have been occupied by men bearing haplogroup I, because today it is abundant in all of the countries surrounding the North Sea.As the meltwaters of the retreating Ice Age glaciers caused sea levels to rise, the low-lying forests and wetlands of Doggerland gradually became inundated. The inhabitants of Doggerland retreated to the higher ground that is now the North Sea coast. I-M253 is especially common today in Scandinavia — it reaches levels of 33% in Denmark and Sweden — and is somewhat common in England, Germany and the Netherlands, where it is found in about 15% of men.
Your maternal lineage may be linked to Marie Antoinette
Because it is so dominant in the general European population, haplogroup H also appears quite frequently in the continent's royal houses. Marie Antoinette, an Austrian Hapsburg who married into the French royal family, inherited the haplogroup from her maternal ancestors. So did Prince Philip, Duke of Edinburgh, whose recorded genealogy traces his female line to Bavaria. Scientists also discovered that famed 16th century astronomer Nicolaus Copernicus traced his maternal lineages to haplogroup H.
