I’m not 100% sure but If you heard about companies/websites that provide DNA testing like Ancestry, MyHeriatage, etc. (actually anything related to genealogy), there is a big chance that they’re based in Ohio Utah and in some way connected (or directly owned) by mormons. Just by now they must have a huge database of people’s DNA

But feel free to correct me, as I said I’m not entirely sure if this is the context
