Maybe not the place to have this discussion as it is completely irrelevant to the topic.
Genotyping (even 10s of thousands) of recovered tissue samples on a forensic STR kit is trivially easy. Genotyping 300 samples from relatives is trivially easy. Statistical matching of STR profiles for identification is trivially easy. Whether you have a pre-existing database would have next to no influence on the technical process. As someone else pointed out above, the difficult bit is finding and collecting the tissue samples.
