Hello
I too am in Australia and I've just started filling in some gaps on our Geaghan side of our family tree. My maternal grandfather was William T Geaghan (b.1904), he was the son of William James Geaghan (b. 1872) and Ellen Ballard (b.1882), and grandson of William Thomas and Kate. Would love to know if we are related and to fill in more gaps if you have info.
