Below is a engraving, published in 1857 of the Mummell Estate, near Goulburn.
My ancestor, Thomas Abberton, settled in Mummell in around 1852/3 after he had arrived form Ballynakill, Co Galway. He and his wife Mary Torp(h)y raised a large family, ran the post office and donated land for the school.
