Based on online resources only, the connection seems to work as follows. The Northwick Park art collections were formed mainly by:
- John Rushout (1769-1859), 2nd Lord Northwick. He died unmarried and was succeed by his nephew:
- George Rushout (1811-1887), 3rd Lord Northwick, who married Elizabeth Augusta Warburton, a widow, in 1869. They had only one child, who died young. When the 3rd Lord Northwick died, the title became extinct, and the inheritance passed to Augusta's son-in-law, by her first husband (Augusta's first husband was George Drought Warburton (d.1857), by whom she had two children, one of whom, Augusta (d.1941), married Lord Edward Spencer Churchill (d.1911), father of):
- Edward George Spencer-Churchill (1876-1964)
An interesting side-note is that the 2nd Lord Northwick had acquired Thirlestaine House, Cheltenham, to house part of his large, and growing, art collection (a guide printed in 1846 listed 500 paintings). After he died, intestate and unmarried, the house and its contents were sold, and the auction catalogue after his death put the number of pictures at "exceeding fifteen hundred"; the house itself was bought by our old friend Sir Thomas Phillipps.
