We need to increase the Khmer DNA pool to help people who are missing a relative. You don't need to match the precise person you are looking for. It can be enough to receive even a match to a sibling, or 1st-3rd cousin of the person you are looking for, who happens to be in the database to start research. Get in touch with them and ask them questions; find your way to the relatives you are looking for. The odds of finding a relative of the person or people you are looking for are increasing every day, the more Khmer people take tests and thanks to projects like the DNACambodia project.
