Kristina Nez Begay does appear to be Dineh on her father's side only, but seems to have grown up far away from Four Corners. She does have a relative named Ernie Begay in Tuba City, though most of her family is in MN or Oregon. The first link that comes up for her is...interesting.
https://www.pureromance.com/kristinanezbegayThat site does wedding and engagement parties and bachelorette parties. She also sells a long line of sex toys, dildos, vibrators, plugs, lubricants, lingeries, bondage gear. There's no sign she's another Harley Reagan though. She just has two different ways to make cash.
Her shame on site has nothing remotely traditional or genuine there. That includes "Peruvian shamans." The only things possibly being Peruvian NDN are some textiles.
I see some "aromatherapy dreamcatchers," a "celestial bell" with a Muslim symbol, Euro faux-pagan oracle cards, ionic body charger, "Florida water" whatever that is, lavender detox bath, abundance cards, a third eye book, chakra pendants, even (you can't make this up) "poo spray." Spray deodorant for farts?
So that makes faux-NDN, faux pagan, faux Muslim, faux Hindu, and lots of general Nuage gibberish and altmedicine that's just useless if you're lucky. That, plus fake medicine wheel and shamanic healing classes, are more than enough to put her in Frauds. She doesn't have the excuse of age, she's in her early 40s.
