Royal Family of Hyrule
The Hylian Royal Family has featured strongly in a few Zelda games, including Ocarina of Time and The Minish Cap. The royal family always contains a princess called Zelda, and usually a King of Hyrule. In The Adventure of Link, a Prince of Hyrule is mentioned. Zelda's mother has never made an appearence. Although, Tetra does have a portrait of a young woman in her room and it can be assumed that this is her mother.
There is no current proven family tree or bloodline, due to a lack of information regarding Zelda's mother, or either of her parents parents. Without this information, it is impossible to construct a comprehensive family tree.
