Hi There Julie.
You have all the details of Daniel Macfarlane correct,I don't know were his wife Susan is buried she died a good while later in about 1911.
Daniel and Susan are my Great Great Grandparents, I used to go to Morgan for all my school hollidays when I was young. I now live in Melbourne Victoria but get back there every so often, I was over there in early August and did a little cleaning up of the grave.
the grave you saw is only the surround that was moved years ago to make way for the football oval, Daniel is still under the old oval, this was what my Grandfather told me wen I was little, this used to be the original Morgan cemetary. I hope you have a little more history now, please feel free to email me at email@example.com
Cheers for now Robert Mcfarlane or BOB.
