Talk:Mary Watson-Wentworth, Marchioness of Rockingham

This portrait has been wrongly attributed on Wiki to Mary (Liddell Bright) Second Marchioness of Rockingham. It is in fact her mother- in- law, and mother of Prime Minister Charles Watson-Wentworth, Mary (Finch) Watson-Wentworth and wife of the first Marquis Thomas Watson-Wentworth. A portrait of the latter pair by Philippe Mercier hangs on the wall at Wentworth Woodhouse. It is clearly the same woman. And examination of the painters' dates and both Mary's dates also proves it would have been impossible to be the second Marchioness.
