James Morris was born on January 19, 1752, on his father's farm in
Morris (then South Farms) in Litchfield County, Connecticut. Shortly after his birth, he was baptized by the pastor
Dr. Joseph Bellamy in Bethlehem's old
meeting house. He was the eldest child of Deacon James and Phebe Morris (née Barnes) and had a younger sister, Lucy, who was born two years after his birth. His parents were both deeply religious, which was typical of New England farmers at the time. His father, who was described as a "devout man," served as a deacon for the church. Morris was the third James in his line, following his father and grandfather, who were also called James. Morris's paternal great-great-grandfather,
Thomas Morris, was an English shipbuilder who immigrated to
Quinnipiac (now New Haven), hoping to continue his trade in the New World. He arrived in Boston aboard the ship
Hector in 1637, and later purchased a tract of land on what is now known as Morris Cove, due to its timber and fertile soil. He remained there until his death in 1673. The earliest evidence of the Morris family in South Farms comes from a 1734 land purchase, when John Morris, of East Haven, bought land from John Bird at the south end of
Bantam Lake. James Morris, Jr., (1722–1789), Morris's father, received most of his land from his uncle, John, on his death in 1744. Soon after this grant, James, Jr., built one of the first houses on the property. His home was located to the west of an old highway that ran through land now owned by
Camp Columbia. In 1751, he married Phebe Barnes, the daughter of Thomas Barnes, at the
First Congregational Church in Litchfield. When Morris was nine, his father built a new, much larger home just north of his birthplace, with a design that young Morris should live in half of it. As the only son, his father couldn’t bear the idea of him leaving home for a formal education, envisioning Morris as “his earthly prop on which he might lean in old age.” An idea Morris himself found unbearable. Through these studies, Morris hoped to eventually become a minister. He was put under the tutelage of Thomas Miner, a divinity student of Bellamy's, and continued with his studies until the spring of 1770. He spent the season studying under the South Farms minister Dr. Salmon Hurlburt, but made little progress, as his efforts were constantly disrupted by household chores. That fall, Morris relocated to Judea to study under Rev. Daniel Brinsmade, where he found yet another instructor in Mr. Nathan Hale (1742–1813), saying of him, "Mr. Hale was an accurate scholar and an able instructor." ==The War==
