Mexican Family in Saint Paul Minnisota

<

To my eyes this appears to be two Mexican families posing for this photo ,possibly two siblings and their spouses??The woman have similar features.One friend who is from Mexico viewed this photo and said that maybe they could be “Indio’s” as he put it in Spanish meaning Indigenous persons from South America.Most likely they are Mexicans of Indian decent.
Very interesting family Portrait

There is what looks like a tear in the lower left of the photo but that blemish is part of the print.I think the original glass negative was broke and then the print was made.
