About ten years after the arrival of the Manchesters, Samuel Hadlock arrived at Sand Point with his children and three nieces. He established a lumber mill at Wasgatt Cove, over what is now called the Mill Brook. Hadlock was a successful businessman and eventually built a house that was valued at $2000. In 1789, Samuel Hadlock murdered Eliab Gott after Hadlock had fought with a number of other men in the village, as well as assaulting Comfort Manchester. This detail was seldom talked about for the next two hundred years, but it has been a topic of interest in the last decade, and recent research has uncovered much information about the murder, and those involved. Hadlock was executed in 1790 in Pownelboro for his actions, and his descendants stayed in the area for a few years afterwards. But after the Hadlock house burned in 1797, and the mill washed down stream in 1798, Samuel Hadlock Jr. left Northeast Harbor.
Local historians are unsure of the location of this mill, which was one of many that were constructed on Mt. Desert Island in the late 18th century.
