Sir William Pickles Hartley founded the Hartley's jam empire.
The Hartley family had lived near Pendle since sometime around 1620, and began as fairly modest local grocers in the district. Wycoller Hall was built by the Hartley family at the end of the 16th century.
As the business grew the family moved into the wholesale trade, and a chance event in 1871 started the Hartley business rolling, as, so it is said, a supplier failed to deliver a batch of jam and William was forced to make his own. His jam, marmalade and jelly sold so well that he continued to make it. Hartley began to develop his business by producing his own fruit and packaging it in his own distinctive earthenware pots.

Please note, there is a small chip on the inside rim of the jar, 12 oclock on the photo, (it may well be an original chip) but otherwise the jar is in very good clean condition.
