Jon Snow and Prince Daemon Targaryen are distant generational ancestors and descendants within the sprawling, complex lineage of House Targaryen. Spanning centuries apart—with Daemon featuring prominently during the Dance of the Dragons era and Jon living during the final eras of the main series—Daemon sits far back on the family tree as a multi-great granduncle to Jon's direct ancestral line, linking them through centuries of royal intermarriage and dynastic descent.
