Even with everyone’s DNA, identifying biological relationships within this group is going to pose a major challenge for DNA analysis specialists. It’s common for girls to be married to their uncles or first cousins, and common for full and half sisters to be married to the same husband. Probably some mothers and daughters sharing husbands too, as women are frequently “reassigned” to new husbands, if their first one gets kicked out of the group. And this has been going on for many generations.
Yeah I know, its a big mess and finally someone is willing to do something about it. I say its about time.

There has been a number of studies from the island of Papua in Papua New Guinea on the indigenous population, shows a reduced Y Chromosome population in relation to the amount of Mitochondrial DNA, meaning it could get extremely difficult to pinpoint fatherhood on any child. http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=379223
If there hasn't been a distinct Y chromosome mutation in the about 5 generations or so since the community formed, it could make the DNA evidence almost worthless in a court.
