She was from Oneida and was the first companion of Catherine Tekakwitha. She later became Catherine Tekakwitha’s most faithful imitatress. She was married to a Mohawk of the Mission of Lorette in Québec. He was delivered to drunkenness and debauchery. However she wanted never to leave him with the hope of his conversion from drunkenness and debauchery and did not cease to pray and do penance for his conversion.

As his relatives were at the Sault Saint Louis, which he went there and she accompanied him. But he did change his conduct and ended in renouncing his Faith, and returned to the Mohawks. It was the only place she refused to follow him. She returned to the relatives of her husband at the Mission of Lorette, in the hope to have him return from his debauch. Nearly a year later, which she was told that he was killed by other Natives in a drinking debauch. She was very touched of this death.
Although still young, she renounced marriage and took the part to pass the rest of her life next to the tomb of Catherine Tekakwitha, where she lived as a Christian widow and ended in sanctifying herself. She died some time later.

The only regret that she had in her last illness was to leave her two children, who were a boy of six years old and a girl of four years old, and not to be exposed to later walk the steps of their father, which she demanded with fervour to Our Lord to not separate the children for her mother. Her prayer was executed. Although they were both in good health, they became sick. One of the children died before the mother and the other eight days after the mother left this world.
