Colonel Augustine Warner, Jr, (1642-1681), a planter, was born in British provincial America in what was to become the state of Virginia, to Mary Towneley Warner and Augustine Warner, Sr., who had been born in England.

The senior Warner emigrated to the Virginia colony where he became a merchant, then major planter and politician and served in both houses of the Virginia General Assembly.

A head grant got him 600 acres, which he expanded. Augustine Warner II (1642 – 1681) inherited Warner Hall, the family estate, upon the death of his father in 1674, and further developed the plantation house and property.

He was schooled at Merchant Taylor's School in London (he went to London in 1658).

He married Mildred Reade, daughter of Sir George Reade, by 1666. Like his father, Augustine II, was a member of the King’s Council and also served as Speaker of The House of Burgesses in Williamsburg.

He died at the age of 39 on 19 June 1681 (interred on his estate), predeceasing his wife. Augustine's three sons (Robert, George, Augustine III) died young and unmarried, but he left three daughters, Mary, Mildred, and Elizabeth, who went on to marry and have families.

Mildred married a Washington, and this couple became grandparents of George Washington, the first president of the United States.

Although looted in Bacon's Rebellion, his estate, Warner Hall, survived and has been listed on the National Register of Historic Places since 1980. Abingdon Church, the second building built on land Warner donated for spiritual purposes, also remains in use today. Despite periods of disuse and disrepair, it has been listed on the National Register since 1970.

Warner is the last common ancestor of George Washington and King Charles III.
