However all of that said, I do think this was a mother and her two children disposed of by a husband or established partner.
I see there has been speculation that they may have been Jewish or from the Middle East but I would have though Jewishness would have been picked up in the woman's DNA.
Only one person on Nam Us is a possible for anyone: Olga Mauger, September 1934 https:// 21 when she went missing.(way younger than the age range for the adult, but I'll take what I can get) there's still a very slim chance it's her.
Two of the bodies were laid out next to each other while the third was place on top of them at a right angle.
The area was found off of a hillside trail in an area that did not see much human traffic.
Since DNA could be extracted only for the adult female there's nothing to say that she was the mother of the children. She could also have been aunt or similar relation since so many young women did not marry in the decades following WWI because of the huge losses of young men in the trenches and elsewhere.
This was much more the case in Europe than in the US, but she could of course have been an immigrant as a young adult.
