Hi Chris
Many years ago I did a little bit of work on this Rheese family for my friend Kevin Rheese, who is a descendant of Edward, b 1866. He might still have the information I gave him. If not, come back to me and I will see what I can find. This is a darn difficult family, Edward senior seems a bit mysterious. This is Kevin's phone number: (02) 6238 2260 I think I actually contacted one of the Underwood's back then about Rosa's grave.
Regards
