Hi Maureen,
I'm on the Zeus level of MTA. I wish I had known sooner that doing this would unlock my Native American ancestry matches, I would have done it sooner. I have the Guanches result too, as well as Aztec, Mayan, Inca, Iroquois, Eskimo, Inuit, Amazons, Mikmaq, Siberian/Bering Strait, Kennewick man and Clovis Man.
On Gedmatch, are you matching against the Atunwa Inarru remains?
I'm a related to two of the three remains in Preacher's Cave, a male and female. But I don't know kit numbers to search on GEDMatch.
Here are details about my two Preacher's Cave matches

I can send you screenshots directly from MTA if you want.
