 One of the first of many mills on the Gwynns Falls was built in the vicinity in 1719 by Peter Bond, Gwin's son-in-law.In 1762, a gristmill and stone house was built by Wimbert Tschudi, a Swiss mill owner, and what is believed to be the ruins of this mill may still be seen on the banks of the Gwynns Falls today.In 1779, Wimbert's son, Martin Tschudi, patented a nearby plot of land called Sly's Adventure.
