Hi Irene.
That's quite a story and probably makes for a difficult search.The bad news is that the Harmony's passenger list did not survive. As a matter of fact, only one Scottish passenger list did over a 30 year period from 1813. I've confirmed that with the Beaton Institute at Cape Breton University.
The likely reason for this is that the shipping officer (the individual responsible for such things) was located at then Ship Harbour (now Port Hawkesbury) at the Strait of Canso, approximately 80 miles from Sydney. Such a distance in those days was like being on another planet. Anyway is interesting that the official was located there since Sydney was an older, more developed centre.
So we'll have to approach the search from a different perspective- follow the names that you have provided.
I believe there was a Sydney newspaper in the day and,if so, I am reasonably sure they would have recorded the landing and, less likely, some passenger names. I have already located a confirmation of the landing but without a date other than 1821.
I have been in touch with Highland Village in Iona, Cape Breton but it will be a few weeks before they are up and running for the new season. Like the Beaton, they focus on Cape Breton/Scottish genealogy.
If you have any other information (especially names) that might be helpful.
