Peter,
Thanks for the information, the Irish migration to Australia was substantial, by 1891 Australia had a population of about 3 million and about 228,000 were Ireland born persons, also between 1791 and 1867 40,000 Irish convicts were transported to Australia, we have a great Irish heritage in Australia.
I understand that Thomas Hayes from John Hayes & Bridget Quigley children went the the US somewhere and 5 others children came to the Victorian Gold Fields including my GGGM Catherine Hayes, I have only recently started to research my Irish Roots and learning about townlands, civil parishes, RC parishes, counties, baronies etc, its part of the fun of genealogy, I like having an Irish family connection.
Regards
Gerry
