Your paternal lineage may be linked to many northern European men

If you have haplogroup I1a1b, your paternal line stems from a young branch of I-M253 called I-L22, which likely arose in the last 3,000 years. I-L22 is most common in Northern Europe, but a recent study found that this haplogroup was present in a significant portion of the Partecipanza population living in San Giovanni in Persiceto, Italy. The area of San Giovanni in Persiceto was involved in a migration period in 728 AD, when it became part of the Lombard kingdom, under King Aistulf. San Giovanni in Persiceto was only under Lombard rule for 48 years, after which the Lombards were defeated by King Charlemagne in 776 AD. There are several characteristics of San Giovanni in Persiceto that link it to other Lombard settlements. For instance, some research suggests San Giovanni in Persiceto was the seat of a Lombard Duke between 750 and 800 AD. It is possible that the Lombards who ruled over San Giovanni in Persiceto played an important role in the introduction and growth of haplogroup I-L22 in the region.

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.
