Hi Peter
I think we may be related through the Duhig line, as I too have been told that Archbishop James Duhig is my great uncle (though I don't know that this is technically correct i.e. may be great-great uncle etc)
My mother (late) was Margaret Dique (nee Duhig, married John Dique) and her parents, Frank and Dorren (nee King). She had one brother, Peter. Are any of these name familiar to you?
I would love to hear more about your family and would also appreciate any information you currently have on our ancestors.
Thanks in advance
Joanna
