are you sure you don't mean Jonestown, PA?
Jonestown is in Eastern Pa, not far from Lebanon and New Holland, I don't know of this place, but it did show up on a google search.
There is a farm by that name, if you google it, in Jonestown.
Okay, after looking into this, it is more likely that since these horses are "broker" horses, and being that the Bernville rescue is in a very close "region" to this farm, chances are, the farm is the broker listing them with the rescue. Hence the reason why the info on the papers is listed. Maybe the owners are going this route trying to place them, rather than taking them to an auction.?
