Background
His father was Jean-Vincent d"Abbadie de Saint-Castin and Joseph"s brother was Bernard-Anselme d"Abbadie de Saint-Castin. Joseph was the younger brother of Bernard-Anselme, who was born in 1689. This suggests he was born in either 1690 or 1691.
Career
He was also an Abenaki chief Differing from the Abenaki which would later become the Penobscot Indians. Baron Joseph was the Grandson of the great Micmac Sachem Madockawando, he was Chief of the Tarratines on the Penobscot River.
In 2013 a book was published entitled "The Vikings of Maine" that discussed the possibility of what became of Baron Joseph Saint Castin and his father Baron Jean Vincent Saint Castin.
Chief Joseph Orono appeared on the Maine Frontier soon after no more was heard of Joseph Saint Castin. When Chief Joseph, the blonde hair, blue-eyed Great Chief of the Penobscots died in 1801 it was claimed that he was 111 years old.
Currently the Penobscot Nation claims Chief Joseph was a grandson of Baron Saint Castin, which is easily proven wrong if one takes into account the age of Chief Joseph when he died at being 111 years old.
