I have, using Ancestry.co.uk found a link in my distant heritage to the Prettyjohn (variations: Prettejohn, Petitjohn) family originally located in Devon.
One great source of information on this family, leading all the way back to the 16th Century, is this website:
My only problem is I can't understand the way that the tree is formatted at all.
Is this a fairly standard form of documentation?
I have tried to contact the website owner via the email link on the page, but have heard nothing back in over a month. Can anyone decipher it and explain it to me (bearing in mind I am still fairly new to family history)?
