There is a very real chance that your DNA test results will result in portions of your tree being “removed.”
You will have to remove that part of the tree yourself, but there is always a chance that a DNA test may result in:
- unexpected relatives
- close relatives not sharing any DNA
There’s always the chance that relatives who are really related share no DNA. That is a reasonable possibility once the relationship gets more distant than third cousins. Your siblings and first and second cousins should share some DNA. Be prepared for the possibility that your test results may help you find some new ancestors…and they may cause you to lose a few as well.
We will be discussing analyzing and interpreting your DNA test results in my upcoming online AncestryDNA class.
