I am trying to pin together the disparate lines of Deed and Dade. There is a lack of paper record, or where they exist clarity, over which if any of the lines relate to each other and if so at such point we diverge.
To date I am the only Deed to have taken a yDNA test (no Dade had done so). However, I have been found to belong to a very small yDNA haplogroup (only two known samples to date including myself). This should allow a high confidence shared ancestry if other surname Deed it Dade were found to match and help prove the semi mythological links between our lines.
I should encourage any male descendant of Deed or Dade with an interest in this subject to take a y test for at least 37 markers, preferably more, or if you become an addict such as me then Big-Y or equivalent (this will highlight your haplogroup in much greater detail).
