River Gipping
The River Gipping is the source river for the River Orwell in the county of Suffolk in East Anglia, England, which is named from the village of Gipping, and which gave its name to the former Gipping Rural District. The name is unrelated to the name of Ipswich. It rises near Mendlesham Green and flows in a south-westerly direction to reach Stowmarket. From there it flows towards the south or south east, passing through Needham Market and a number of villages to reach Ipswich, where it becomes the Orwell. The river has supplied power to a number of watermills, several of which are still standing. None are operational, although the mill at Baylham retains most of its machinery, and is the only complete mill on the river.
Harpeth River
Another possible origin for the name of the Harpeth River was presented by Edward D. Hicks in a paper read before the Tennessee Historical Society and published by the “American Historical Magazine” in 1900. Hicks comments upon the influence of classical literature read by learned gentlemen in the 18th Century. One source popular among many in the English-speaking world, including America, was the “Spectator” published by Joseph Addison. The “Spectator” contained articles on philosophy, morals and the classics. In publication number 584, printed in 1714, is found the antediluvian love story of Hilpa, Harpath and Shalum. Harpath comes to an untimely end drowning in a river as he attempted to cross it. “The river is called to this day from his name, who perished in it, the river Harpath…”. Hicks does not offer the claim that this is the definitive origin of the name however he does say it is “certainly appropriate…I submit it as the most probable and ingenious theory I can suggest.” 
It should be noted that early 18th-century maps including Matthew Carey’s 1795 Map of Tennessee as well as that of John Reid, Imlay’s American Topography, Arrowsmith, and Stockdale use the spelling Harpath River which differs from the modern spelling of “Harpeth”. The exception is John Russell’s 1794 map of the Southwest Territory published in London circa 1794. The earliest known written reference is found in the diary of John Lipscomb. His July 1784 entry mentions the “Harpath” river. In addition, contemporary historian Virginia Bowman gives credence to Hick’s theory in her comprehensive book on early sites and homes of Williamson County, Tennessee.
