I bought the Philip Pepper homestead in 1997 from members of the Peffer's heirs, the Sherwoods. It is now known as 80 Aqueduct Drive 17044.
He lived at the site from about 1826 and bought the property in 1832. The property has remained in the family up until 1997. Various family names include Zimmerman, Diebolt and Zimmerman.
I just met a Len Peffer (80+ yrs? old) who was born in the house and still lives in the area.
