    Not related

    According to GEDMatch, the parents are not related. B+ is the blood type of my other sister whose kit might be part of a mix up (same type as our mother). There are other kids on the father's side with a different mother so might see about getting them to take the test too.

    Thanks again to all who are helping me!

      If you're determining paternity based off of military dog tags blood type, don't. My dog tags say I'm A+ but DNA and 2 pregnancies says I'm actually O+. I've found others who were typed incorrectly as well.
