Who was Arthur Onslow, 3rd Earl of Onslow?

Arthur George Onslow, 3rd Earl of Onslow was a British peer. He was the eldest child of the 2nd Earl and his wife Arabella Mainwaring-Ellerker.

On 21 July 1818 he married Mary Fludyer, eldest daughter of George Fludyer of Ayston, County Rutland, esquire and of Lady Margaret Fane, daughter of the 9th Earl of Westmoreland. They had two children -

Mary Augusta

Arthur George, married 1 August 1850 Lady Katherine Anne Cust, 4th daughter of John, 1st Earl Brownslow. He and Katherine Anne had 3 daughters

The 3rd Earl's wife predeceased him on 1 March 1830, as did his son, and so he died without surviving male issue and was succeeded as earl by his grandnephew, William.

He had a large Napoleonic collection and reportedly, on visiting the Louvre with Paul Delaroche in 1848, he commented on the implausibility and theatricality of David's painting Napoleon Crossing the Alps. He commissioned Delarouche to produce a more accurate version which featured Napoleon on a mule, entitled Bonaparte Crossing the Alps. Two versions survive, one at Liverpool and one at the Louvre.
