Madeleine Cahill (a.k.a Maddy Babbit) is the founder of the Madrigal branch, and the fifth (and secret) child of Olivia Cahill.

Madeleine Cahill
Branch:Madrigal (Founder)
Age:Born 1507
Relationships:The Cahill Family
First Appears In:Vespers Rising
Last Appears In:Vespers Rising


After the fire that destroyed the Cahill house and killed their father on 1507, the Cahill children parted ways, leaving their mother Olivia Cahill behind. They were not aware, however, that Olivia had been pregnant with Madeleine before the fire. Madeleine was born in 1515. She was named after her great-grandmother, Madeleine the Matriarch because her mother believed that she would reunite the Cahill family. Olivia and Madeleine later went into a self-imposed exile to the mainland, living under the surname of Babbitt, to avoid Damien Vesper. Though her siblings were not aware of her existence, Olivia told her about them, also teaching her that:

a) Nothing is more important than reuniting their family.

b) She must prevent any single branch of the family from obtaining all the Clues.

c) Gideon's gold ring must not fall into the hands of Damien Vesper, or as Olivia said, "the world will be his.".

According to Video 3: Madeleine on the 39 Clues website, in 1526, when Olivia Cahill died, Madeleine was left in a mildly depressed emotional state, questioning what her mother had taught her.

To this day, the Madrigals continue to pursue the aim of their ancestor, constantly, secretly attempting to reunite the branches of the Cahill family.

On Card 249: Madeleine's Book, Madeleine´s Book, It reads "In the year of our Lord 1507, a terrible fire". It appears that she was married to a man in Britain named Robert Arden sometime before 1537. In 1537, she gave birth to Mary Shakespeare (Née Arden) who later gave birth to the famous poet William Shakespeare. This is because all of Shakespeare's grandparents have been recorded except for his maternal grandmother.

Appearance and PersonalityEdit

Madeleine was a beautiful young woman with thin, shoulder-length, curly reddish-gold hair, heart-shaped lips, pale skin, and brown eyes (as shown in The Black Book of Buried Secrets). She was shown also wearing a white pearl hair-loop and a thin black choker. She wore a tan dress that had a bear, a dragon, two snakes, and a wolf design on it, representing the 4 other Cahill Branches. In The Emperor's Code, Daniel Cahill thought that she looked like his mother Hope, but with hair and clothes from a different time.

Madeleine was taught from an early age to try to reunite her family, which most likely caused her much stress. Being the founder of the covert Madrigals and having lived most of her life in secret, Madeleine was adept in secrecy, much like Fiske Cahill. Similar to Amy Cahill, she was rather shy, worried more than she should, and spoke with a mild stutter. Later, when she decided to commit herself to her cause and later to create the organization that would later become the Madrigals, she became more brave and more confident, again similar to Amy.


The Black Circle Edit

The code in The Black Circle said "Remember Madeleine" in Russian. It also said, "Olivia had another."

There is a bonus video about Madeleine on the website - Video 3: Madeleine.
