I am trying to identify my British great-grandfather. I have investigated him in Japan and narrowed the candidates down to eight. I then checked those eight candidates in detail; seven of them seem not to match, and only one candidate stayed. He is C.Z. Ede (Cecil Zohrab Ede). I checked into him and there is some circumstantial evidence indicating that he is my great-grandfather. However, there is no decisive evidence.
A DNA test (Family Tree DNA-Family Finder) said that a Danish man was a cousin to me but when I tried to contact him no reply came back.
I want to be more sure of my relationship to him. My British friend says that Ede may be a family name of North European origin, and I understand that the family name of Ede is rare in the U.K.
Is it true?
