him. He was commissioner of fisheries from 1866 to 1873; and acting conservator of the River Mersey from 1879 until his death at Tunbridge Wells on 12 March 1888. He had married Sophia Price.

On the same stone is also mentioned William Devereux who died in the island of Crete (12 November 1852) at the age of 3 years and 6 months. Role in discovery of Troy One of the maps made by Thomas Spratt known as "Spratt's Map" was used by archaeologists Heinrich Schliemann, Wilhelm Dorpfeld, and Carl Blegen, which contributed to the discovery of Troy, because the name Troy with a question mark was added by a German professor of classical antiquities working with Spratt over the spot of the real Troy. He had added it, because it was above the ruins of the identified Greek city of Novo Ilium (New Troy). Observing the map, Schliemann saw Troy with a question mark and decided to begin digging, which led to the discovery of Troy. See also Xerxes Canal References Bibliography Volume 1; Volume 2.
