Admin HistoryThe papers of the Treacher family are of particular importance for the history of the Thames Navigation, as successive generations of Treachers served as surveyor and in other posts for almost ninety years, including the years of the Thames' greatest commercial use, and were responsible for building many of the pound-locks on the upper Thames. The first John Treacher (1736-1802) was a carpenter from Sonning, whose relative lack of education is evident from his handwriting and eccentric spelling. His first work for the Thames Navigation came in 1773; and from c.1786 he was put in charge of the lock-building programme for the river above Reading, under surveyor John Clarke. In 1791 Treacher was appointed General Surveyor for the upper district of the Navigation, and in 1795 he became General Engineer of the whole Navigation.
He died in 1802, and was succeeded in these posts by his son, another John Treacher. In 1821 the administration of the Navigation was reorganised, and Treacher was appointed General Surveyor of the whole Navigation. Between 1813 and 1824 he was also the surveyor of bridges for the county of Berkshire. His son George was a highly skilled builder and engineer, whose work on his own included the building of Hungerford church tower in 1812. In 1824 George was appointed assistant surveyor to the Thames Navigation, and when his father died in 1836, he was the obvious choice to succeed him as general surveyor. In 1856 he also became general receiver (of tolls etc) for the Commission. He resigned in October 1862 due to illness apparently caused by stress, and died early in 1863. This was the end of the Treachers' long association with the Thames Navigation Commission; descendant Llewellyn Treacher later said 'The family held tight to the commission throughout its existence... Frankly it was disastrous to them'. George Treacher's son John became a market gardener in Twyford, and died in 1907. His son Llewellyn assisted his father, and spent much of this time in amateur historical, geological and archaeological research. Some of his historical notes are found here; the majority of his papers were deposited separately and have been catalogued as D/EX 564.

A brief pedigree can be seen in the record office paper catalogue.
