Nicolas Buteau married Catherine Guichelin 23 October 1669 at Sillery, Canada.
While Catherine is Pierre Buteau's mother, it is not clear who his father was because of the following reported in Rene Jette's Genealogical Dictionary:
Catherine Guichelin was ordered to strand before the Conseil Superieur of Canada on 19 August 1708 on charges of living a scandalous life of prostitution.
Nicolas Buteau's marriage to her was annuled 2 March 1697.
Jette states because of the above, Pierre's father is unknown.
This Pierre Buteau is not the one recorded in Thomas J. LaForest's Our French Canadian Ancestors, Vol XX, Chapter 6. Wife's and children's names are different.
