A linguistic family (or language family) is a group of languages related through descent from a common ancestral language or parental language, called the proto-language of that language family. Note: Two languages might belong to one language family. These languages may share some traits, but they are not the same language!  Source: https://en.wikipedia.org/wiki/Language_familyA few more maps and information:

The below map shows some of the distinct language families spoken across Turtle Island (North America). Note: This map does not show individual languages, just Indigenous language families. Many distinct Indigenous languages are spoken across Turtle Island. Language revitalization efforts play an essential role in retaining language diversity.
