Your paternal lineage may be linked to the Cham
One of the many populations harboring members of haplogroup O1b1a1a1a1 is the Cham ethnic group, a group of people who speak Austronesian languages in Mainland Southeast Asia. Austronesian languages make up a language family that is extremely large and widespread, comprising over 350 million people on islands such as Madagascar, Easter Island, and many others. However, Austronesian languages are less common on mainland Asia, with a notable exception being the Chamic language. Research suggests that ancestors of the Cham people migrated from Southeast Asian islands to the mainland around the year 500 BCE, and that early Cham populations quickly began mixing with indigenous southern Vietnamese populations. As a result, the Chamic language now has words that were borrowed from languages spoken by indigenous Vietnamese people. It is likely that an ancestral Kinh population was one of the populations that mixed with the Cham people shortly after their migration to mainland Asia.
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 Lacour 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.
