I did the Y-DNA on FamilytreeDNA and I am pending on Ancestry.com. There were about 20 individuals who reported but many were private and those who were public represents three groups J1 R1 and I1, The largest number were in my group (I1) this group is small in England at 12% and originated in Nordic areas (Baltic Sea) The largest group in England is R1 and covered settlers from the last Ice age, who came from Iberia (Spain). I think the J1's came from Italy. See Brian Sykes' Seven Daughters of Eve.
The Y-DNA points to Nicholas Cady roots in Anglia likely Dane or Jute
