Your paternal lineage may be linked to the Han Chinese

Haplogroup O-Page23 has been found in several populations of the Han Chinese ethnic group. The ancestors of the Han, called the Huaxia, lived in the upriver basin of the Yellow River 5,000-6,000 years ago. As agricultural technology improved, the Huaxia spread east and south, and became the Han Chinese. Over the last 2,000 years, there have been three major migrations of the Han southward. The first of these migrations occurred during the Jin Dynasty from 317 to 420 CE, when nearly one million people moved south. A second migration occurred during the Tang Dynasty, after the An-Shi Rebellion, between 755 and 762 CE. The last migration occurred during the Southern Song Dynasty, from 1127 to 1297 CE, when nearly 5 million people migrated southward. The Pinghua, a branch of Han in which haplogroup O2a2b1a1 is particularly common, may be descendants of indigenous minority groups that adopted Han culture during one such major migration event.

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 Lou 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.
