I have just come across this site (and topic). I am descended from a Brogan family that settled in the Goulburn district of NSW, and have been told they originated in County Clare. I have seen a headstone in a cemetery at Collector (near Goulburn) NSW for James Brogan, died around 1870, and in the burial ground at Spring Valley in the same area a headstone for Mary Brogan, died around 1912. My memory of these dates is a little fuzzy as I no longer live in that region. I know the Mary Brogan buried at Spring Valley was my paternal grandfather's grandmother, that she married William Payne who died around 1870 (from whom I take my surname) and I believe bore him 12 children, but was buried under her maiden name.
