James- I have been experimenting with the Kennedy Sample file in a few Family Journal Report styles.
Can you define whether you are trying to get endnotes in Descendant, Family, or Reverse Register order? Mod Register, Register, or Custom Style?
There are some differences in the way references are cited in each RTF output. If you are able to print sample Kennedyreports to file, (MSWord, deselect Automatic Launch)and then open them in Word's "Recover text from any file", you can do a search for either "footnote" or "Rachlin" or even "ibid" to see the differences in the RTF Coding for yourself.
