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 appearance. Although, Tetra does have a portrait of a young woman in her room and it can be assumed that this is her mother.

Ganondorf's Conquest
The first records of Hylian history begin with

Twili Occupation
The Twili race from lands west of Hyrule conquered Hyrule castle under the leadership of Zant, quickly defeating the Hylian armed forces with their unconventional arms and tactics, and forced the Hylian monarchy to surrender. The Hylian monarchy, after surrendering, existed as a figure hood under Princess Zelda, but the real power belonged to Zant and his army. After conquering Hyrule Castle, Zant's armies pushed swiftly east and south, until controlling all but the southernmost portions of Hyrule.

Ordonian Liberation
Midna, heir to the throne of Twili, was exiled and traveled to the highly isolated town of Ordon, the last major area in Hyrule not to fall to Twili forces. Immediately after the arrival, a small attack group of Gerudo horsemen entered Ordon. Midna defeated the small force, and subsequently Ordon pushed North into Faron forest, and liberated it from Twili rule. Rapidly, the Ordonian forces recaptured a devastated Kakariko village and restored its ties to the Goron civilization, allowing bombs to be manufactured. From this staging ground, Ordon liberated the rest of Hyrule, with Twili rule completely eliminated from Hyrule.

North-South Split
Hyrule was split into two sections, the northern section under Gerudo rule, and the southern section under Hylian military rule. The Northern section contained most of Hyrule's defensive and administrative structures, whilst the Southern section was the commercial and residential sphere. The Southern section had a large influx of Goron merchants who brought with them bombs from Kakariko, a powerful and decisive weapon not yet in Gerudo or Twili capabilities. South Hyrule was plagued by enemies on its Northern, Western, and Eastern borders. Because of this, South Hyrule maintained a very large standing army, equipped with long spears and chain mesh armor.

Ordonian Restoration
When Ordon and their allies finally captured Hyrule castle, the Hylian monarchy was restored. Little is known about the time directly following the restoration.

Decline
Ultimately the Hylian monarchy would be done in by dramatic climate changes that led to much higher sea levels and the flooding of traditional Hylian centers. As societies began to rebuild, no single world government emerged. The closest thing to a ruling family was the government based in the Forbidden Fortress, which was composed of various races descending from the inhabitants of Gerudo Desert. They had a wide-reaching navy, as well as many heavily armed outposts, and even built small wooden "submarines" where the bulk of the ship was below the sea. The descendants of Hyrule, and to a very small extant Kakariko (Northern areas of Hyrule) established a thriving merchant society of Windfall Island (North in The Great Sea). The society was distanced from their Hylian past. Another society, most likely descending from Ordon and Kokori, existed at the Southern Tip of Hyrule, called Outset Island. They put a higher value on their Hylian past then their Windfall island counterparts. They still celebrated ancient Hylian symbols, and looked highly upon "The Hero of Time", eventually trying to implement the myths themselves.

Attempts at Restoration
When Link of Outset ransacked and pillaged the forbidden fortress, he began a concerted effort to restore Hyrule's old monarchy to its former glory. Eventually, he defeated Ganondorf and asked the King of Hyrule to return to the throne. The King of Hyrule, however, refused, saying that people should not spend their lives trying to rebuild the past. He chooses to die with his kingdom as the last reigning Hylian monarch. Although Tetra exists as a proper heir to the throne, she follows her fathers decision not to restore the monarchy, and continue her life as a merchant. The Kingdom of Hyrule is no more.

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.
