How to document a person with multiple official names?
My paternal grandfather had multiple name changes over his lifetime. At least four name changes. Different official documents (birth, naturalization, census, marriage, death, etc.) have different names. For example, his given name was Pasquale which he changed to Charles at some point. The last name changed dramatically as well.
How is this tracked in a family tree? Is it his final name that is used since it match the next generations?
