The only way to change the page url (and thus filing order) is to delete it after copying and pasting to a new page. To create a page that shows up correctly in the index, do a search for “c:Cole Helen Curtis” and then there's a button to create this page (you need the “c:” or other letter to get it to file correctly or else it puts the page at the bottom of the list). Copy and paste the content into new page. To delete old page, delete all content on the page and then save; it is now deleted.
