Dear Carol, 1) Are you suggesting that even though we did not match the descendants of this family, we may be related to them? There are more than one Rogers family in the world. There are many people in the world that have your same 12 marker that you match to. Some of our Hendricks families match perfectly up to even 25 markers but they separate into another group when you do the 37 marker case. This is not always the case but it happens. Matching to that Rogers family you are excited about with a 12 marker match maybe yours. It also may not be yours. The 12 marker test gives false positives because it matches to to many people, it may match to a Smith family. Did you do a Y-Search? This a good test to show you what I mean. Some 12 marker DNA profiles yield prolific family connections but they really are not. You have to do more testing to prove and sort out the false positives. As you put in more markers in the Y-search you get less and less possible connections. My Hendricks family is very unique even back to Western Europe we do not have a 37 marker DNA pattern that matches to anyone else. Y-searches verify this. However if I only do a 12 marker Y-search I pull up about a dozen people I match to. Why? Back in time we were all kin. The 12 markers are more common and do not separate people out. You have to test more markers to separate people out. We get Smiths, Jones and others who match to the Hendricks family with a 12 marker test. Am I communicating? Many other DNA groups get the same results. 2) Are you saying that we are NOT related to the families we matched in the 12 marker test? Or that we are only POSSIBLY related to them? Again I am saying, to know you have a match that is not a false positive, you have to do more testing to be certain. We have about 57 Hendricks DNA participants. We have 22 different Hendricks groups. How did we know this we do only 37 marker testing. How many Rogers groups do you have? One, two or 22? A 12 marker test does not separate out groups very well. Now if there is not many Rogers in the world then you don't have many groups. So you could conclude that since there are not many Rogers then a 12 marker test would be valid. From what I know about just the Rogers in Virginia this is not the case there are many Rogers Families. How do you know which one is yours? DNA matching is a start but family lineages is also necessary. Go to FTDNA and look at the Smith families. Access the site and see how many groups they have. How did they separate them out? Not with just 12 marker test. Some may be possible but this is generally not the case. DNA markers could be contrasted by describing a person. Each marker shows some characteristics. The more markers the more characteristics you have. What I am telling you is not Herb Hendricks opinion or any truths I established it is a fact in DNA testing. I'm just trying to tell you the facts. To many people have read the Genographic Project propaganda, spread it around and think 12 marker DNA testing is the only thing they have to do. Not so. God Bless.

I'm not trying to be impertinent. I honestly want to understand what you are saying. And there may be other people out there in as much of a fog as I am. I've never heard of the Genographic Project. My cousin was tested last summer, and no one has suggested that he have more testing done. All the matches we got had the last name "Rogers" which is our family name. He did the 12 marker test primarily to find out if we were related to the Benjamin Rogers family that had settled close to our family in MO. We had been stewing over this one for years. It turned out that we did not match that family at all. 1) Are you suggesting that even though we did not match the descendants of this family, we may be related to them? I thought it very encouraging that our ancestors had migrated to the same areas as the 4 Rogers families we actually did match and which I've already discussed to some extent. Our brick wall had been Joseph Rogers, born in SC in 1788. But we had suspected that his family was originally from Virginia because that's where his wife's family (Mullings and Garrett) was from. Two of the families we "matched" had come from Virginia and gone to Tennessee. Joseph served in the Tennessee Militia during the War of 1812. So we have a few more similarities than just height and weight, so to speak. We have last name, 12 marker match, and geographic locations. So, bottom line: 2) Are you saying that we are NOT related to the families we matched in the 12 marker test? Or that we are only POSSIBLY related to them?
