Hello Lynnette,
Thank you for your question.
Information on the title page is limited to the five segments outlined in section 2.3.3 of the Braille Formats Principles of Print-to-Braille Transcription, 2016.
The guidelines for information located on the book cover, jacket, or inside cover details can be found in section 2.8. I suggest applying these guidelines to the epigraph.
Mike
