Edward Mackenzie (1811-1880)
Brother of William Mackenzie
1880 Obituary 
Mr. Edward Mackenzie, of Fawley-court, Henley-on-Thames, has passed away at the age of 70. He had a severe paralytic seizure about four years ago, but he recovered from this, and was in the enjoyment of good health until three weeks ago; upon returning from his estates in Scotland, he was visited with a renewal of the seizure. His system had been too much shaken to resist this second attack, which ended fatally on Monday last.
He was the youngest son of the late Mr. Alexander Mackenzie, C.E., of Fairburn, in Ross-shire, and was twice married; first, to a Miss Dalziel, of the Craigs, County Dumfries; and secondly, to Miss Ellen Mullett, who survives him.
He leaves behind him a colossal fortune, made as a civil engineer and contractor. He was a man of mark in connexion with his elder brother, the late Mr. William Mackenzie, and the late Mr. Brassey, in the early and palmy days of the railways, they being the contractors for gigantic works in France and England. They were all men of great administrative powers.
Mr. Mackenzie lived for a quarter of a century at Fawley-court, which estate he purchased on retiring from business. The house abounds with valuable paintings and works of art; it was built by Sir Christopher Wren after the demolition of the former mansion during the great rebellion. Mr. Edward Mackenzie was a magistrate and deputy-lieutenant of the county of Oxford, and served the office of high sheriff of that county in 1862-3.
