Hi Annem
I'm sure have all this, but I found it interesting anyway, so posting as others may also find it so:
Pratt, George Murray
Born: 14 JAN 1843
Died: 14 OCT 1922
Father: Pratt, George Charles, Marquess Camden 2nd, b. 2 MAY 1799
Mother: Murray, Harriet
George's Older brother John inherited the title as 3rd Marquess Camden and was married to a Spencer-Churchill
(does that bring in Princess Diana's family to their tree?)Source:

There are portraits of his grandfather here, including a good bust:
