Wallace Collection Wallace Collection The Wallace Collection is an art collection in London open to the public, housed at Hertford House in Manchester Square, the former townhouse of the Seymour family, Marquesses of Hertford. It comprises an extensive collection of fine and decorative arts from the 15th to the 19th centuries with important holdings of French 18th-century paintings, furniture, arms and armour, porcelain and Old Master paintings arranged into 30 galleries. It was established in 1897 from the private collection mainly created by Richard Seymour-Conway, 4th Marquess of Hertford (1800–1870), who left both it and the house to his illegitimate son Sir
Marquess of Waterford of Ireland (created by writ ca. 1650). Lord Tyrone was succeeded by his fourth but eldest surviving son, the second Earl, who also inherited the title Baron La Poer from his mother in 1769. In 1786 he was created Baron Tyrone, of Haverfordwest in the County of Pembroke, in the Peerage of Great Britain. Three years later he was made Marquess of Waterford in the Peerage of Ireland. The titles descended in the direct line until the death of his grandson, the third Marquess, in 1859. The late Marquess was succeeded by his younger brother, the fourth Marquess. the titles
