Your paternal lineage may be linked to the Yayoi

Haplogroup O1b2a, a branch of haplogroup O, is closely related to several haplogroups that are commonly found in Japan. Haplogroup O is closely associated with Kyushu, Japan's third largest island, and makes up over half of all men in Japan. Although haplogroup O is prevalent in Japan, it likely only entered Japan during the Yayoi expansion about 2,300 years ago. During the Yayoi expansion, people entering from the Korean Peninsula brought wet rice agriculture, weaving technology, and metalworking technology to Japan. The Yayoi expansion began on the island of Kyushu, where haplogroup O is very common today. It is possible that some of the early members of O1-F3356 were involved in this major shift, which quickly and dramatically altered Japanese culture.

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 Yamamoto 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.
