Biographical/Historical note

William ap John Thomas (fl. 1556) of Treowen, Monmouthshire, alias William Jones, was the first of his family to assume a surname, and left issue by four wives and at least one concubine. William's eldest son, John Jones (d. pre 1609), succeeded his father at Treowen. Blanche, the only child of William's first marriage, had Castell Arnallt and married Rowland Morgan of Machen, Monmouthshire. The property devolved on their descendants, the Morgan family, barons Tredegar. Philip Jones (d. 1603), John's half-brother, made a large fortune as a London merchant and became a member of the Grocers' Company, and was MP for the Monmouth boroughs 1588-1593. He built a town hall and a market house in Monmouth, left money to build a market house in Abergavenny and to make the Monnow bridge at Monmouth free from tolls. John's son, William Jones (d. 1640), acquired Hendre-obaith following his marriage in 1599 to Jane, daughter and heir of Moore Gwillim, MP for Monmouth. The estate also acquired the Penllwyn-sarph estate following the marriage of John Jones ([c. 1687]-1788) with Florence Morgan. He was succeeded by his son Philip Jones (d. 1782), who married firstly Catherine, sister and coheir of John Wyborne of Hawkwell, Kent. Their son John Jones (d. 1828) of Llanarth and of Upton in Berkshire was succeeded by his eldest son John Jones (1790-1848). The Jones family were a long standing Catholic family. John Jones's son, John Arthur Jones (1818-1895), obtained a royal licence in 1848 for himself and his brothers and sisters to assume the surname of Herbert in lieu of Jones, being the senior existing branch of the house of Herbert. In 1846 he married Augusta Hall, the only surviving child and heir of Benjamin Hall (1802-1867), Lord Llanover. Their eldest son, Major-General Sir Ivor John Caradoc Herbert (1851-1934), became Baron Treowen in 1917. He married Albertina, daughter of Albert, Lord Londesborough, the second son of Henry, 1st marquis Conyngham, and had a son, Elydyr John Bernard Herbert (b. 1881). The family were renowned Catholics.
