Ten years ago, the EFA paid for a DNA test for members through Ancestry to determine if the Eddy males who participated would localize to one of the three known lines. Under the direction of Gary Eddey and Frank Eddy the results--now unfortunately lost by the commercial lab--found that indeed all tested appeared to localize to one of the three lines.
The lines are represented below as those descended from William Eddye of Bristol England, John of Taunton, MA, and John of Woodbridge, NJ. The results confirmed that the EFA’s original genealogists had correctly identified three distinct Eddy lines. Perhaps we will find that with more specific DNA data, this will not be the case, but for now we believe good, original source genealogical work is as good as DNA results.
