This is Entally, built about 1819 by Thomas Reibey, son of horse thief & businesswoman Mary who is on our $20 note. It's an Indian name, Bengali it seems from the Wikipedia article, after a "neighbourhood" in Calcutta. Or more likely, after Thomas's father's business that was named after said suburb of Calcutta. His father had been in the East India Company and made use of his connections there to establish an import business in NSW. It is the next generation that had most influence on the property though, the son, also Thomas, and his wife Catherine.
There are many outbuildings, laid out in yards. I am doing individual posts for some buildings.
