If you had your dna tested or not they have everything!! If you ever step foot in the Drs/hospital & born at the hospital they have it! From urine samples & blood thats more than enough to search you & your family history. This is why they want us to have our kids in the hospitals, soon as babys born they inject babys with poison & collect the heal prick blood samples it’s wild!!! Soon as I gave birth to my twins I ask for the placentas in 2017 they about nutted & became mean as fk!!
Don’t be to worry they have nearly everyone’s dna for sure the ones that stayed away from dr n hospitals n had home birth are prob the only humans dna not touched
