Nathaniel is in business on his own account, builds more windmills, and more colonial buildings including the Rum Hospital, Parramatta and Liverpool Parsonages and starts the Liverpool Hospital. Has disputes with Colonial Architect (former convict for forgery).
His children are also carpenters/builders and build more windmills and start a ship-building business. His wife Olivia and some children go to Tasmania and farm. They supply hops to James Squire (yes, the Fifty Lashes bloke, whose daughter married one of the Lucas boys).
A grandson of Nathaniel and Olivia's becomes a NSW Member of Parliament (MLA) who saves the Jenolan Caves from mining and has the Lucas Heights nuclear reactor named after him.
These days there are over 25,000 descendants of the original couple and one source states that 1 in every 799 Australians in a descendant.
I'm jealous of all of that, but also that she has a family that so many other people have done extensive research on which they share with others.
Well done Colleen, great story!
