Hello MatthewCameron and welcome to Rootschat,
Don't know if you noticed , but the original question posed and the replies were posted in 2010.
Two of the contributors haven't been active on the site for a couple of years , but if their email address is still active they should get an email alert advising them someone has posted on this thread.
Thank you for posting the info you have found.
I'm a Loudoun lassie born and bred and I have to admit Pischineuch/Pischeineuch has me stumped

- never heard of it, I'm afraid.
Looby
