Your paternal lineage may be linked to Ötzi the Iceman

Ötzi the Iceman was discovered in 1991, protruding from a snow-bank high in the Alps near the Austrian-Italian border. His 5,300-year-old remains turned out to be so well preserved that researchers were able to construct a detailed account of his life and death. Chemical analysis of Ötzi's teeth indicates he came from the Italian side of the Alps. He had suffered during the year before his death with whipworm, a stomach parasite that was found in his digestive tract. Yet he was fit enough to climb 6,500 feet in elevation during the day or two before he met his end in a rocky alpine hollow. Ötzi apparently was murdered, struck by a stone arrow point that was found lodged in his left shoulder. The twisted position of his body indicates that the murderer, or one of his accomplices, pulled the arrow's shaft out of Ötzi's prone body.Yet whoever killed Ötzi did not take the valuable and finely wrought copper axe that he carried with him — an indicator that at the age of 45, the Ice Man may have been a figure of some importance in his community. Recently, scientists who were able to extract DNA from Ötzi's remains discovered that he belonged to a paternal lineage that stems from haplogroup G-M201. Today, Ötzi's lineage reaches its highest levels in Sardinia and Corsica, and was once common among early European farmers.

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.

What do people with the surname Grimaldi have in common?

Spoiler alert: it's complicated. People with the same last name are usually no more genetically similar than a randomly sampled group of people from the same population. That said, people with the same surname are more likely to have similar ancestries than randomly sampled individuals. The reason is the tendency of people with similar cultural or geographical backgrounds to preferentially mate with one another. That's why people who share a surname may be more likely to share traits and tendencies in common than people within the general population.
