HI Sandy,
My name is Joanna. I live in Brisbane, Australia.
My mother (late) was Margaret Dique (nee Duhig). Her father was Frank Duhig and mother Dorren (nee King). Although I don't have documented family tree (slowing but surely trying) I too have been told Archbishop James is my great uncle (though I don't know that this is technically correct i.e. may be great-great etc). Just to check we are takling about the same person. Please view
http://www.library.uq.edu.au/about/duhig.html and let me know.
Look forward to talking more.
Jo
