Ute-Aztecan language family is one of the most successful language to ever spread across the continent of America. The language family spread like wild fire originating somewhere between the border of the U.S. and Mexico in particular the Sonoran desert that crosses over both countries around 5,000 years ago. The language family could be found as far west in California and as far south in El Salvador, Nicaragua and Honduras and as far north in Idaho and Oregon and as far east in Oklahoma. Several language family have survived and several also have unfortunately gone extinct. Nahuatl is considered the largest Ute-Aztecan language today.

There are only a few language family in the world that equal this feat of expansion during it's time. Example, Austronesian language family expanded throughout Southeast Asian continent and island archipelagos, throughout the Pacific Islands, as far west in Madagascar and as far south in New Zealand. The family language began expanding at least 6,000 years ago.
I posted the Austronesian map separate as you can see it's located in the next post because the Wikipedia map of Southeast Asia won't allow me to post it here.

Another example is the Indo-European language family which originated in Urartu or somewhere in the Eurasian Steppe of Central Asia around 5,000 years ago. The language branches are predominantly found throughout Europe, Western parts of Asia and throughout the Americas and it represents 47% of todays languages.
There are a few more examples of language family like this as well
