Mirabella Plunkett

Mirabella Plunkett (b. 1839) was a witch, famous for falling in love with a merman. After she was forbidden to marry him, she transfigured herself into a haddock. She was featured on a Chocolate Frog Card and on a portrait hung at Hogwarts Castle.

Early life
Ms. Plunkett was born in the year 1839 under a pure-blood or half-blood family.

Holidaying in Loch Lomond
At some point in her life, she travelled to Loch Lomond on vacation. During this vacation, the witch met a merman and, eventually, fell in love with him. The feelings were most likely reciprocated by the merman.

Planning to marry
Mirabella was more and more in love with the merman. They decided to marry, to Mirabella's family displeasure. They were opposed to the whole marriage and, as Mirabella did not listen to them, they eventually forbid Mirabella to marry the merman. She became distraught.

Turning into a haddock
Her family did not back away with their ban on the marriage. Upset, Mirabella transfigured herself into a haddock and was never seen again. It's unknown if she ever returned to her merman lover once in her haddock form.

Legacy
After her disappearance, Mirabella was not forgotten; she was included in the Chocolate Frog Cards collection. Also, there was a portrait of her hung at Hogwarts Castle, guarding a secret shortcut between the first-floor landing of the Grand Staircase and the Entrance Hall side room. The password required to gain access to said shortcut was Haddock.

Etymology
The name "Mirabella" is derived from Latin mirabilis "wonderful".
