After the death of Queen Jaehaera Targaryen in 133 AC, Lady Johanna set aside her war with the ironmen long enough to write the Hand that her daughters Cerelle and Tyshara were maidens of noble birth and marriageable age.
Not long after the Maiden's Day Ball was announced, Tyshara was found abed with a groom. Tyshara claimed that the groom had climbed through her window, but Grand Maester Munkun's examination found her maidenhead to be broken. However, it is still likely that the groom was planted, as it was heavily rumored that Lord Unwin Peake, the Hand of the King, set to ruin various maidens to promote his own daughter as Aegon III's second queen. Moreover, it is quite common for highborn ladies to lose their maidenheads while horseback riding.
