I have just visited the convictrecords.com.au website and noticed that someone has made a contribution to the website (for John Pye of The Lady Kennaway) that is directly copied from my article on John Pye in this Blog and from my book, “Tapestry, John Pye of Windsor, NSW.”

Do you know anything about Thomas Pye (who changed his surname to Clark) and his wife Isabelle Clark? I was searching my “Clark” line and it showed Charles Gipson Clark, James Thomas Clark, and then Thomas Pye Clark.
I think his parents were William Pye (Deborah), and his John Pye (Mary Nutley), but it just seams like something is really off in this.
Sorry, I have not come across your family at all.
What country, county or state did they live in?
