In his father's will, Anthony Junior was left his main estate at Cyfarthfa in Glamorgan, including the ironworks, and also half of the nearby Hirwaun works.
However, upon coming of age, Anthony seems to have had little desire to continue his father's business and he leased the Cyfarthfa ironworks to Richard Crawshay.
In 1806, he sold his share of the Hirwaun works to his brother, Thomas, and, with the proceeds, he bought the Mathews' estate at Aberaman, also in Glamorgan, where he lived when in Wales.
[2] When he died in 1827, he was buried in the family vault at Shaw-cum-Donnington near his brother's home at Donnington Castle House.
[3] He married Elizabeth, the daughter and sole heiress of Richard Ramsbottom MP of Woodside House at Old Windsor in Berkshire, and they had eleven children together: Gen. Anthony, Col. Charles, George William, Richard Thomas, Philip, Elizabeth (who married Thomas Thornhill), Mary, Fanny, Emily (who married Thomas Peers Williams, Father of the House of Commons), Henry and William.
