I am reading William's 1910 History of Frederick County and on p. 321 he says: "Point of Rocks is a village at the eastern foot of Catoctin Mountain where that mountain ridge comes to the Potomac. The place was made famous by the litigation between the Baltimore and Ohio Railroad Company and the Chesapeake and Ohio Canal Company . . . in 1832 and for a year or more pending the litigation Point of Rocks was the western terminus of the Baltimore and Ohio railroad where freight was gathered from a wide expanse of territory for shipment to Baltimore. As may be imagined during that time it was an exceedingly lively village with an active trade. Just one mile east of it is Washington Junction where the main line of the Baltimore and Ohio joins the Metropolitan branch. It is an important place and has largely superseded the village. . . The original village was known as Trummelstown and was laid out on the main road from Washington to Hagarstown about a mile from the present village.
