You probably know all this already -- but just in case. I come at this from my experience as an interpreter charged with maintaining complete confidentiality.


What counts as "identifying information" depends on your kid's culture/community. Parental connections are super-strong signifiers in many cultures; uncle/aunts are more important in others. The smaller the community, the more readily any tidbit serves as a unique identifier.

So switching community membership could make a big difference.

Because you have an ethical concern, I think this is a situation where a beta reader would be very helpful.
