Maggie was born in 1832 in Ireland. She had difficulty dealing with authority, on a parental and community level; she was born with the gift to sense when someone was lying, and in those situations, she felt compelled to point out the lie. Her accuracy made people uncomfortable around her, especially close ones. Though this often led to punishments, sometimes quite severe, she did not relent her nature. Certain people thought of her as a devil because of her gift.
The Great Famine in the 1840s decimated her village, and her family was forced to leave for America in search of a better life. Her family didn't have enough money to transport every member and Maggie was subsequently left behind to take care of her maternal grandparents, mainly—as she knew—because her parents felt uncomfortable with her sensibility to lies. Siobhan and Liam found Maggie alone on the road to Cork, nearly dead from starvation. She was almost immediately able to recognize them as non-human. Siobhan, curious with her ability, offered to make her strong enough to live. Maggie sensed that she was telling the truth and so agreed. Siobhan's mate, Liam, was not convinced about having her with them, but Siobhan persuaded him otherwise. She deeply enjoyed their company because they were routinely honest both with themselves and each other. Over time, even Liam had warmed up to her.
Whenever they encountered another vampire or human, she could use her gift to sense their honesty, and so Siobhan and Liam trusted her judgment.

In Breaking Dawn, Carlisle and Esme seek the help of Maggie and her coven and ask them to go to Forks. Once they arrived in town, Edward and Bella tell them about their half-vampire daughter, Renesmee, and because of her ability, she is able to determine the baby was not an immortal child and that the Cullens are telling the truth about their innocence.
She stands as a witness for the Cullens to try and save the child from the Volturi's accusation. When co-witness, Alistair, fled out of fear for the Volturi, she declares her determination to stay behind and help.
She, like the rest of her coven, returns to Ireland at the end of the story, after the situation was resolved peacefully. She gives Renesmee and Bella a hug before setting off with her coven.
Maggie is very thin, standing 5'2", thin and with bouncy bright red curls, and not as physically imposing as Siobhan or Liam. In the movies, her hair is brown but still very curly.
Maggie is very righteous, headstrong and believes in justice. Whenever someone lies to her, she will loudly point it out even when it got her into trouble, usually with authority, both on a parental and a community level, which resulted in her receiving punishments that were sometimes quite severe. This is why she feels comfortable with Siobhan and Liam, because they are always honest both to themselves and to her. She is also quite taken with the Cullen family because of their honesty both to her and to each other.
Powers and abilities: lie detectionEdit

Maggie is gifted with the ability to sense when someone is telling lies. This power manifested from her potent ability to read people's lies as a human. This becomes very useful when helping the Cullens, as when the Volturi came for Renesmee and Aro was about to tell her she was going to be fine, and Maggie knew that he was lying.
She can also read a person's appearance and actions to know if they are lying as well. As a side effect to this gift, she would feel physically uncomfortable with any kind of deception.
As a human, Maggie was the first child of a large Irish family.
Siobhan is Maggie's creator, and leader of the coven.
Siobhan found Maggie in Ireland, dying from starvation inhabiting the country at the time. Maggie could tell that she and Liam were not human beings because of her power. Siobhan, fascinated with her ability and feeling pity for the young one, offered to change her into a vampire so that she will never feel hungry or weak again. Feeling no deception from her words, she agreed.
After she was changed, Siobhan treated her like a daughter (naturally assuming the switched roles she once had with her own mother), and Maggie is happy to have found someone who speaks and acts on their intentions.
Liam is Siobhan's mate, and therefore a prominent part of the coven.
Unlike Siobhan, who was eager to let Maggie join their coven, Liam was initially reluctant to having her (mostly because he did not want to share Siobhan's attention with the young girl). However, Siobhan managed to convince him to give her a chance, but he only agreed begrudgingly.
Liam eventually saw the usefulness of having a talented member, and began to accept Maggie as one of them and treat her like a sister. Like Siobhan, he acts and speaks on his intention, which pleases Maggie.
