An ancestor is a person from whom one is descended, typically more distant than a grandparent. Ancestors can include great-grandparents, great-great-grandparents, and so on. They are part of a family lineage and contribute to a person's genetic heritage and cultural background. Understanding one's ancestors can provide insights into family history and traditions. Many people explore their ancestry through genealogy, which is the study of family lineage and history. This can involve researching family trees, historical records, and DNA testing. Learning about ancestors can help individuals connect with their roots and understand their place in the world.
