These Lines have been DNA Tested but do not currently match with any existing group.
Much of the original information included within TRP's DNA pages was copied by TRP volunteers from the web pages of The Reeves DNA Project on Rootsweb in 2011 and 2012. The primary Reeves Y-DNA Project information is currently to be found on our companion project at https://www.familytreedna.com/groups/reeves/about. If your line is represented here, why not Join Us and contribute proven information about your extended family?
- Are you related? Yes, but . . . .
- Can you adopt their research results? Not necessarily.
When you were tested you ordered the results in terms of a certain number of markers (e.g., 12, 25, 37, 67).
The more markers you test and match, the more closely related you are to the person you match. If you are a perfect match with someone at the 67-marker level there is a very high probability (95%) that you share a common ancestor within the last seven generations. There is a 90% probability that the common ancestor can be found within five generations. And, there is a fifty percent chance of sharing a common ancestor within the last two or three generations.
Of course, if your results vary by one or more markers, then the greater the variation in your tree from others in the group. At 37 or 67 markers people with a perfect match are tightly related. If you differ with someone by only one marker (genetic distance of one) you are closely related. If the difference is as much as seven markers you are probably related, and with a difference of 10 or 11 markers there is no relationship.
Even with a perfect or near perfect match at the 67-marker level, it is unwise to rely upon DNA test results as the sole basis for adopting someone else's family tree as your own. You are both on the same tree, but it may require going back 140 years (7 generations) or more to find the branch where your common ancestor resides.
DNA testing is an amazing tool to use in the quest to identify ancestors, but it is only a tool. Old fashion research is still required to find positive links among specific individuals.
