Ashbridge House was built in 1769 on the northern section by one of Rees Thomas's sons, William, and his grandson, Rees Thomas III.
Peter Pechin purchased this property in 1850. He left a farm to each of his four children, giving the Rosemont property to Rebecca Emily Pechin Ashbridge.
Her husband, Joshua Ashbridge, already owned forty adjoining acres on the south, and the tracts took on the name Ashbridge.
A small section of the Ashbridge land was deeded to the Pennsylvania Railroad for a station with the understanding that it be named Rosemont. Both Montgomery Avenue and Airdale Road were constructed through the property, which had a long straight lane to Roberts Road.
Rebecca and Joshua Ashbridge's three daughters inherited the tract in 1891 and, with foresight, planned wills as early as 1906, when Mary died.With the death of the third sister in 1940 the farm was left to Lower Merion Township to be used for recreation.
Now named Ashbridge Memorial Park in memory of the soldiers of World War I, the "Tribute Walk" was built by the Rosemont-Villanova Civic Association to honor those who fought in World War II.
The area of rare specimen trees, some ancient and somecarefully selected by the late Jack Kenealy, tree warden of Lower Merion Township, has been called the "Kenealy Arboretum".
