Vallon’s reference is the Priest from Gangs of New York fictional universe Gangs of New York is a 2002 American epic historical drama film directed by Martin Scorsese and written by Jay Cocks, Steven Zaillian and Kenneth Lonergan, based on Herbert Asbury's 1927 book «The Gangs of New York». Priest Vallon was born in 1807 in Dublin, Ireland to a family of Irish Catholics. He emigrated to the United States to escape the great famine of the 1830s and 1840s, settling in the Five Points slum of Manhattan, New York City. There, he became a respected leader of the Irish immigrant community, and he was nicknamed "Priest" for his devout Catholicism; however, he was no clergyman, fathering a son whom he named Amsterdam and coming to lead the Dead Rabbits, a gang of Irish Catholic immigrants formed to protect the Irish immigrant community from nativist violence. He became rivals with the Protestant Natives gang, led by William Cutting, and they planned to decide their dispute once and for all on 6 February 1846.
