Sorry, I do not have Warnock information for you. Have you tried the new method of research using Family Search. They have allowed researchers to have access to certain wills and deeds into that have not been indexed yet. This experimental project uses A.I. to search and read documents for you, but only certain countries can be accessed. But you are in luck, Australia and New Zealand are part of the project. To enter his experimental project, use the website of familysearch.org/labs. You can use your same password that you use for Family Search. It is fantastic.
Good Luck.
