The problem with DNA testing for genealogical search or Research is it's a High Cost for Minimal return. I'm made up of my mom & my dad, They're from their mom & dad, and so on and so on. But the test is only good for my Hill line which makes the test a Minimal return. It also doesn't take in to account for the fact that while our kin migrated across this U.S. they did so in groups. Those groups was not always comprised of just family members. If a man & his wife died on the trail leaving an infant, that infant was taken in by someone else that was not kin. Now when they gave said infant their name. That infant grew up not knowing any better but went by the last name JONES but was really a DAVIS. He would show up with different markings then the family that raised him. You get the picture. Not to forget the many other reasons that a child might not be the blood kin of the man who called him his own. The only way that DNA would be a Minimal help in genealogical research is with a Database that all the DNA info goes into. Not just one for Hill's or Smith's or whoever. They would have to be compared to all to pick-up these Scenarios. No, I have found that there is only two things that DNA testing is really good for. 1. For testing if a child is really the Father's. 2. People in prison and when someone is arrested,(Taken along with their fingerprints). With their DNA along with their fingerprints put into a central database. Then when a crime is committed by repeat offenders and DNA evidence is found at the scene but not FP's. Jay
