The place to find all this out is to look the farm up in the Valuation Rolls. These were published annually by the local authorities as the basis on which rates (local taxes) were levied. They list, for each habitable house, the names of the proprietor, tenant and occupier.
For example House2000's people might be occupiers of a house tenanted by Patrick McGill and owned by Ross's Dairies.
There are almost certainly copies in the Stirling or Falkirk archives, and possibly in public libraries in that area as well. There are definitely copies in the National Library of Scotland and I think in the National Archives of Scotland.
None of which is terribly handy if you don't happen to be in central Scotland. You might need to find someone (professional searcher or kind soul) who would be willing to look them up for you. Be aware that this will involve ordering and waiting for a large book for each year, leafing through the book to find Rashiehill (properties are listed by parish, and not in alphabetical order within parishes) and noting the relevant surnames, then doing the same with the next year and so on.
