Your paternal lineage may be linked to The Ancient One

When two college students stumbled upon a human skull on the banks of the Columbia River, neither the students nor the police who responded to their 911 call could have imagined the archaeological significance of this rare discovery. The skull — along with about 300 other bone fragments found near Kennewick, Washington — belonged to a 9,000 year-old nomad who Native Americans have dubbed "The Ancient One." Based on skeletal clues, The Ancient One (also known as "Kennewick Man") likely swam, wielded a spear, and hunted coastal fauna for the greater part of his lifeInitial craniometric studies suggested he descended from ancient Japanese and Polynesian-like people and had little in common with living Native Americans. This claim — refuted by the Plateau tribes of the Pacific Northwest — became the center of a decades-long legal battle over the provenance of the remains. When The Ancient One's genome was finally sequenced in 2015, the evidence revealed he was genetically most similar to modern-day Native Americans. In fact, local tribes were found to be direct descendants of a population closely related to The Ancient One; in 2017, he finally received a proper Native American burial. This critical discovery helps illustrate a genetic continuity between ancient and modern-day Native Americans. Furthermore, his paternal line belonged to haplogroup Q-M3, the predominant lineage among Native Americans today.

Your maternal lineage may be linked to some of the first Americans

Though the Ice Age was beginning to retreat when your A2 ancestors first entered North America, there were still massive barriers blocking their way. Glaciers and inhospitable climate covered much of the continent, blocking entry into the interior. Nonetheless, researchers have found evidence that a wave of American founders migrated over 13,000 kilometers to reach southern Chile in only 2,000 years, a blink of an eye in the story of human migration! Their highway to the south was the coast of the Pacific, stocked with fish, diverse marine mammals, and other valuable resources in the rich kelp forests of the upper latitudes and in the abundant fresh-water rivers near the equator. Because of this rapid movement south, the A2 haplogroup and its diverse branches are found throughout North and South America.

What do people with the surname Monroy 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.

Are health conditions linked to the last name Monroy?

The short answer is that, if there is an association between surname and health, it's usually more about your ancestry than your name. Individuals with a given surname are no more genetically similar than the general population but often have similar ancestries. The populations of people associated with those shared ancestries often have sets of genetic variations, also known as alleles, in common. Some of those alleles are associated with a greater likelihood of developing certain diseases.

Age-Related Macular Degeneration

Y402H variant

Age-related macular degeneration (AMD) is the most common cause of irreversible vision loss among older adults. The disease results in damage to the central part of the retina (the macula), impairing vision needed for reading, driving, or even recognizing faces. The 23andMe Health + Ancestry DNA test includes the two most common variants associated with an increased risk of developing the condition: the Y402H variant in the CFH gene and the A69S variant in the ARMS2 gene.
