Madrigal
Lucian, well that is Madrigal, a type of Lucian.
Lucian (Luke Cahill) Ekaterina (Katherine Cahill) Tomas (Thomas Cahill) Janus (Jane Cahill) Madrigal (Madeline Cahill)
Okay, here's the truth by studying the Cahill family tree of the Oh family and Grace's family. Grace's grandfather Henry was a Madrigal and married another Madrigal: Flora, who had James Cahill, Grace's father. But Flora died and Henry married an Ekat; Hae Oh. They kept the name Oh and had their offspring, Gordan and Bae. Then Gordan had Alistar. So Grace is a Madrigal and not an Ekat, it's just that James and the Oh twins are half brothers.
The Madrigal leader was formerly Grace Cahill, but since shes has past, Amy and Dan are actually the branch leaders. I wonder if Amy and Dan know this.
Amy and Dan Cahill are part of the Ekaterina branch in the 39 Clues series. The Ekaterina branch is known for their intelligence and passion for knowledge.
Amy and dan are madrigals, the man in black is their great-uncle, fiske cahill, Nallie is a madrigal too, and Fiske and nellie are the new legal guardians of Amy and dan.
Their branch is....... madrigal (srry i wanted it to be dramatic) :D
Amy and Dan are part of the Cahill family, a secret society in The 39 Clues series. They belong to the Madrigal branch of the Cahill family, one of the most secretive and enigmatic branches.
no
The Man In Black is Grace and Beatrice Cahill's brother. He disappeared for 50 years and his identity is found out in Storm Warning. He is a Madrigal and is said to have many similar traits to Amy and Dan. In Into the Gauntlet, he and Nellie Gomez will get joint custody of Amy and Dan.
Fiske Cahill/ Man in Black is a Madrigal
Amy and Dan are Madrigals. The Madrigals decended from Madeline Cahill. Olivia Cahill (the original cahill) was pregnant with her when Olivia died. Madeline then decided to carry out her mother's wishes. Madrigals try to keep the other branches from finding all the 39 clues. Hope this helps! :)
