[2] Her father was the second of the four sons of the 6th Duke of Richmond (1818–1903), and his obituary in The Times called him "a notable social figure, whose popularity it would be difficult to over-estimate".

In September 1910, Lady Algernon Gordon-Lennox took firm action to quell a rumour that her daughter was engaged to marry Edward Turnour, 6th Earl Winterton.

Lady Algernon Gordon-Lennox contradicts the report current in London, and referred to in these dispatches last week, of the engagement of her daughter, Ivy, to Earl Winterton.

On 12 August 1915, Ivy Gordon-Lennox married William Cavendish-Bentinck, Marquess of Titchfield (1893–1977), son of the 6th Duke of Portland and his wife Winifred Anna Dallas-Yorke.

[10] From 1922-43, Lady Titchfield was a political wife, her husband representing Newark in the House of Commons and serving as a Junior Lord of the Treasury under Stanley Baldwin and again under Ramsay MacDonald.

She intended it to help artists by providing affordable work-space in quiet surroundings, to support the survival of specialist craft skills in an age of mass production, and to improve public access to the visual arts.

The Foundation was granted a long lease of some properties at Welbeck and it now maintains three sets of studios there, with space for up to thirty artists and craft-workers, plus a gallery and craft shop.
