A couple recently gave their wedding guests one of the coolest wedding gifts. Each guest walked away with their own ancestral ethnicity breakdown. The couple used the service MyHeritage DNA test. Business Insider writes, "Along with the wedding invitation, each guest received their test kit in the mail ahead of the wedding. Guests collected their DNA samples with a quick swab of the cheek and mailed their sample to the MyHeritage DNA lab. The bride and groom then surprised their guests with their DNA results, which were revealed to each of them in a special room during the wedding reception."
