If you are surprised to hear that there are McBreartys in Australia I was wondering if you knew that there are quite a lot of us in New Zealand too. I am a descendent of James McBrearty who was from Greenock, Scotland in 1837. He moved to New Zealand and was married here in May 1868. He had many children, one of which was called James Wilson McBrearty who then had a son and named him James Michael McBrearty (which was my grandfather). He also had a son and named him James Robert mcBrearty (my dad). The last James McBrearty in this line is my brother. (As you can see we like the name James)
I have a lot of information relating to my family if you are interested in writing to me.
