South of Valley Green Inn, Livezey House, also known as Glen Fern, was most likely built in the early 1700s. Originally owned by James Claypool, one of William Penn’s resident land commissioners, the property had at least seven owners before being purchased in 1747 by Thomas Livezey a Quaker miller, farmer, justice of the peace and provincial commissioner. Livezey’s grist mill, the stone ruins of which can be seen today next to the house, was not only the largest of dozens of mills scattered along the banks of the Wissahickon, but it was said to be the largest mill in the Colonies. In 1868, the Livezey House and mill were sold to the Fairmount Park Commission.
