Nicholas,
I have just seen your message on the notice board and it has intrigued me. I thought I had a complete family tree - at least for those born prior to 2003 - of the descendents of John Duhig the father of Archbishop James Duhig but you do ao appear on it. I would like to correct this deficiency.
Do you know the name of your Duhig great-great grandfather - Edward (Timothy), Martin or Patrick - they were the only three boys in that generation besides the Archbishop? If you could send me the first names of your father and grandfather, I can probably work it out.
Do you want any further family information? There are some early details in my reply to Sandy Duhig from which I have not had a response.
