A person's identity is established through evidence. Usually that evidence comes from multiple record groups which when studied together either forges stronger links between family members, or weakens links (and confusion reigns.) Sometimes there are records about the same person which disagree. Become familiar with available tools from online family trees that can help to logically build the evidence to strengthen a claim to a specific ancestor.
