O'Rourke Families

I would love to contact any O'Rourkes who have origins in or around Maybole, Ayrshire, Scotland. I am tracing my Family tree and need help on my Fathers side. I have posted another topic in the name HUTTON/LOGAN.
My Father was born 7th December 1905 and his mother Annie O'Rourke would have been about 16 years old at the time. She had a sister Margaret. His father was John Hutton who is believed to have migrated to Canada.
My Father emigrated to Australia in 1923 and lived in Grafton in northern New South Wales where he met and married my mother. His aunt Margaret Logan came to Australia and also lived in Grafton until her death in the 1970's.
This has the makings of a great story. all contributions would be gratefully accepted.
