A family tree is a visual representation of a person's lineage, showing how different family members are related to one another. It typically starts with a single individual and branches out to include parents, grandparents, siblings, and descendants, illustrating the connections across generations. Family trees can be simple or complex, depending on the number of generations and family members included. Creating a family tree can help individuals understand their heritage and family history. It often involves research into ancestors, birth records, and marriage certificates to accurately depict relationships. Many people use family trees to preserve their family's legacy and share it with future generations.
