I had an uncle Ralph Pusey of the Chester County Puseys. He was married to Anna May, maiden name I am not certain of, but will provide what information I have about him.
With regard to Caleb Pusey, he was William Penn's business partner, having arrived in Pennsylvania in 1682. The following is from the Caleb Pusey House and Landingford Plantation Web site at http://www.delcohistory.org/fcph
Built in 1683 and occupied by Caleb Pusey, this is the only building still standing which can claim documented association with the Proprietor, William Penn, and which he is known to have visited on several occasions. This unique English Vernacular house stands beside Race Street, the small road once paralleling the millrace that brought water from Chester Creek to power the mills.
"Landing Ford" was the name Pusey gave to the 100 - acre plantation adjoining the mill site which Penn had deeded to him and which he cultivated to raise food for his large family.
Pusey had come to Pennsylvania in 1682 to serve Penn as manager and agent for the Chester Mills, the first official Proprietary saw and grist mill to be established by Penn in the colony.
Being new to Ancestry.com, I am in the midst of learning how to use the site's research database and will provide copies of several birth/death/marriage certificates in my possession. They are from the personal files of my late father, William Robert Klaus (d. Oct. 15, 2005).
