Under French régime the age of majority was 25. This applied to both male and female. Age at which they could marry is a different issue, girls could marry starting at age 12, boys age 15 or 16 (I forget which, the issue didn't arise much).
After the English conquest, it did some hop-skipping around
En Nouvelle-France, la majorité est établie à 25 ans[; 21 ans de 1763 à 1774 ; 25 ans de 1774 à 1782 ; 21 ans de 1782 à 1971. https://fr.wikipedia.org/wiki/Majorit%C3%A9_civile
Since 1972, age of majority in this province has been 18. Prior to that it was 21. My brother married right after the law changed, would have had to wait otherwise as my parents were not going to sign the paper allowing him to marry. My parents were right. She dumped him a few years later.
don't worry about it, you should have seen what Google translate did with one poor guy. XYZ fils became XYZ wire
