Task: Question Answering
Input (English): Passage: Set in New France in 1634 (in the period of conflicts known as the Beaver Wars), the film begins in the settlement that will one day become Quebec City. Jesuit missionaries are trying to encourage the local Algonquin Indians to embrace Christianity, with thus far only limited results. Samuel de Champlain, founder of the settlement, sends Father LaForgue, a young Jesuit priest, to find a distant Catholic mission in a Huron village. With winter approaching, the journey will be difficult and cover as much as 1500 miles.
LaForgue is accompanied on his journey by a non-Jesuit assistant, Daniel, and a group of Algonquin Indians whom Champlain has charged with guiding him to the Huron village. This group includes Chomina – an older, experienced traveller who has clairvoyant dreams; his wife; and Annuka, their daughter. As they journey across the lakes and forests, Daniel and Annuka fall in love, to the discomfort of the celibate LaForgue.
The group meet with a band of Montagnais, First Nations people who have never met Frenchmen before. The Montagnais shaman, the "mestigoit", is suspicious (and implicitly jealous) of LaForgue's influence over the Algonquins. He accuses him of being a devil. He encourages Chomina and the other Algonquins to abandon the two Frenchmen and travel instead to a winter hunting lodge. This they do, paddling away from the Frenchmen. LaForgue accepts his fate, but Daniel is determined to stay with Annuka and follows the Indians as they march across the forest. When one Indian tries to shoot Daniel, Chomina is consumed by guilt at having betrayed Champlain's trust. He and a few other members of the Algonquin tribe return with Daniel to try to find LaForgue. 
Question: What is the first name of the person whose trust was betrayed by Chomina?
Output (English): Samuel.
