Good to hear from you. The Willeys on the Hope with Hugh and Elizabeth Dunn were cousins. The Joseph on the Hope is an older brother of my gg grandfather Henry Willey who came to Australia with his wife Jane (Lock) on the Nestor in 1854. Joseph settled in Tasmania and Henry at Macedon in Victoria. The Frederick and Joseph on the Hope were sons of Robert Willey son of George and Sarah (Webb) and they settled in the Bellarine Peninsula area in Victoria.
If you are interested I can send you more on the Willeys as a gedcom file. I am not sure if I can do it through this site. My email is robinob at bigpod.com Replace the at with a @ of course.
All the best
5th cousin (I think)
