From Finding UK record(s) of British great-grandfather with children born in Japan during 1890s? I have received the information of the person with the possibility of great-grandfather.
However, I have a bigger problem from here which is whether he really is my great-grandfather because there was a brother to him in the information.
If I can find his brother's descendants, then I may be able to learn the kinship with DNA testing.
How can I find the living descendants of this great grand uncle?
I was born and grew up in Japan where research is easy for me but I do not know the best way in Britain and Australia.
C.Z.Ede is the name of the candidate for my great-grandfather and his information can be found at https://familysearch.org/ark:/61903/1:1:VB6B-BD9
There is also a Mr Peter Zohrab site (http://zohrabfamily.atwebpages.com/ztbltre3.html) which mentions "Sydney Cuthbert Ede, Eagleville Station, Talbotville, Victoria, Australia".
Mr Peter Zohrab from that site suggested that I look for descendants of Sydney Cuthbert Ede in Australia or New Zealand. However, I have not yet found any. I am also inquiring at the church in which he was baptized.
