Aegon V's cousin Bryden

[Nic G]

In TMK Egg calls Bloodraven cousin, but he is his great uncle (by being his grandfather's halfbrother) unless Daeron is the Dragonknights son then they would would be cousins twice removed right?

Or is that about him imposing as a Plumm and Viserys Plumm could be called a cousin?

[Lost Melnibonean]

I am sure Daeron was the son of the Dragonknight and that Daemon Blackfyre was the son of the Unworthy. In Samwell I, Feast 5, we learned that Daeron II was rumored to have been fathered by Aemon Targaryen of the Kingsguard called the Dragonknight, and not by Aegon IV the Unworthy. And we recalled that even Maester Aemon leant credibility to the rumor when he told Jon Snow of his own heritage way back in Game. Sansa had told us back in Storm that Naerys was Aegon's sister and queen, and that he never harmed her, perhaps out of fear for their brother the Dragonknight. And the very attentive reader would have recalled way back in Game, when Sansa was about to go riding with Joffrey near the Trident, she told us that Prince Aemon the Dragonknight championed Queen Naerys's honor against evil Ser Morgil's slanders. A little later, when the Ned told Sansa that her engagement with Joffrey would soon be over, she suggested that Queen Naerys loved Prince Aemon the Dragonknight. In Clash, she suggested that Prince Aemon the Dragonknight cried the day Princess Naerys wed his brother Aegon. A song was sung about the romance during the Battle of the Blackwater. As Meera was telling Bran about the Tourney at Harrenhal, Bran was telling us that the Dragonknight once won a tourney as the Knight of Tears, so he could name his sister the queen of love and beauty in place of the king's mistress. A few chapters later in Feast, Arys Oakheart suggested that the tale of Prince Aemon's treason with Queen Naerys was only that, a tale, a lie his brother told when he wished to set his trueborn son aside in favor of his bastard. However, it was clear that Arys was fighting his lust for Arianne, and losing miserably, so his denial lacked at least some credibility.

GRRM uses the term cousin loosly.. Brynden is Daeron II's brother, and Aegon is Daeron's grandson. So Aegon could call Brynden great-uncle.

But, Aegon could also look from the common ancestor, Aegon VI, in which case they would be cousins, first cousins twice removed.

[Ferocious Veldt Roarer]

I wouldn't read too much into it. Egg certainly wasn't suggesting that Daeron (and, by extension, Maekar and Egg himself) had been illegitimate. Could be that he chose the word "cousin" to make the impression of a conversation between two equals.

Or could be just author's error.
