John de Marquet Blaxland (also known as John Blaxland Junior or John M. Blaxland) was the eldest son of John Blaxland, elder brother to Gregory Blaxland.

John Junior lived an explorer's life besides being a major landowner with extensive pastoral interests. Various place names throughout the Hunter are named after him. He is heavily documented in family history and colonial history.

He lived a solitary life. As the eldest son, he did not marry nor did he produce any children (that we know of). He had good relationships with the local Aboriginal tribes around the Duck River area and it is said he discovered the Bulga Pass due to his local indigenous connections.

He outlived his father dying in 1840 at the age of 40 years old. But what did he die of? What was the most common disease that a healthy young man at the age of 40 would die in the colonies? There is a mention of his internment that was printed a couple of weeks after his death which was well attended by his relations and his sisters' families (Justice Dowling and Colonel Breton). There was also a mention of how he was in his Hunter house with a Superintendent William Merton, and two convicts burgled and stole their personal effects while they were in residence. Was he gay?

The newspaper, on his passing, stated that his death will be "long" felt - from family members and servants alike. For so well-connected a person, to attain the age of 40 without any attachments is curious. All his other siblings married. He was friends with James Macarthur, George Augustus Middleton and other personages of the early colony.

I welcome any thoughts...
