They traveled with Penn on his ship The Welcome,[a] and brought with them prefabricated grist and saw mills which they planned to erect in the province and Pusey was to be the manager.

He was also involved with the local Quaker community, and wrote a number of pamphlets, several in defense of William Penn.

It became common practice, in Pusey's time and earlier, to use the place of family origin as a surname.

The initial construction of the main house consisted of a single room which had a large attic or loft that was used for storage and sleeping and had a gable roof.

At a later (unknown) date, another room was constructed which shared that western wall, so that the chimney was then in the center of the house.

It also contains a large iron basin called a stand-kettle[8]: p12  on the back side of the east room's fireplace.

There is a small access door on the front of the house to the space below the stand-kettle where the fire is set.

It's also been suggested that the west room construction was necessitated by the destruction of the east wing in a fire,[2]: p4  which likely happened in or after 1723[10]: p15 , when Pusey no longer lived there.

After Pusey left in 1717, the Landingford property was owned by a succession of people, including industrialist John Price Crozer.

It was discovered early on that there used to be a cellar below the east room of the house which had been filled in and forgotten, probably in 1899 (see foundation drawing).

This was fortunate from an archaeological perspective because the fill that was used was from a refuse pile containing a vast trove of artifacts that had been discarded over a period of many years.

It extended significantly further in the front than the other rooms and was accessed by a separate entrance with a stairway of 5 or 6 steps going down to the floor which was below ground.

Since all lead was collected during the revolutionary war for making bullets, this would suggest that the destruction of the east wing occurred between 1723 and 1776.

It has been suggested (though not proven) that the fire was caused by a small copper still, the remains of which were found beneath the collapsed chimney.

If sufficiently violent, such an explosion could have been responsible for the chimney collapse and also the deformation of the eastern wall of the main house.

A newly minted coin from 1699 was found at the bottom, possibly dropped or thrown in by William Penn who returned from England in that year and visited with Pusey in December.

Artifacts were found from the entire time period that the house was occupied, although a large proportion were from 1752 to 1786.

[10]: p2  The property, including the Crozer Schoolhouse next door, was acquired by the Friends of the Caleb Pusey House, Inc.

[16] Period English furniture and other items were added to the house to show how it might have looked when Pusey and his family lived there.

The loft now has a door on the east end which has to be accessed by ladder on the outside of the house as there currently is no interior stairway.

The race is shown on Samuel Lightfoot's 1730 map, which also shows the Pusey house, Chester Creek, and the mills.

(On current maps, Baldwin's Run enters Chester Creek near the west end of Worrilow Rd.

This site was slightly downstream from Pusey's house and the race was extended to reach it (see 1730 map).

Note that the creek and the mill race flow from left to right on the map (approximately west to east).

Henry Graham Ashmead, in his 1884 book on Delaware County history states: "Doubtless when repairs were made to the mill, in 1699, the rude iron vane bearing the initials W. P. (William Penn), S. C. (Samuel Carpenter), C. P. (Caleb Pusey), and the date, 1699, was placed on the building.

When Richard Flower owned the property the old vane surmounted the dwelling-house of the owner, but on gusty nights, turning in the wind, it squeaked and groaned so noisily that it was taken down.

[12] The Pennock Log House, which was built by a descendant of Pusey's in 1790, was originally located in Springfield Township.
