Right, what DNA can do is help reconstruct a family tree, assuming there are enough cousins out there who have tested and uploaded DNA to public databases. Then genetic genealogy can "close in" on likely families and investigators can interview them to see if anyone existed who fits the profile, and then find out if such person was missing.
And of course, if you have DNA on file, either direct sample or a very close relative, you can compare directly as any of us could who have a "kit" on a site like Gedmatch. Parents, siblings, first cousins, etc would share an expected amount of DNA, so voila. Confirm or rule out. But no, that would not indicate "Born in Cleveland"
