Edward Hussey Delaval, third and last surviving son of Captain Delaval. He was born in 1729, and married Sarah, daughter of Mr. George Scott of Methley, Yorkshire. He only held the estate six years, and then died without any heir on August 14th 1814, aged 85 years, and was buried in Westminster Abbey.
From his mother, he inherited the Doddington estate, which he left absolutely to his only daughter, Sarah Hussey, wife of Mr. James Gunman of Dover and Coventry. She died in 1825, and left the estate to Lieut-Col. G. R. Payne-Jarvis, whose successors still have the estate. This is how the Doddington estate passed from the Delaval family. At his death the name of Delaval died out, and the Seaton Delaval estate passed to another family. It may be interesting to record that Edward Hussey Delaval, who was of a very scientific and philosophical turn of mind - his favourite pursuits being chemistry and experimental philosophy - was the first in Europe to demonstrate the benefits derived from the use of what are now called (lightning rods) in protecting buildings from the effects of lightning, his own house in London being the first in the world to be so protected
