Thanks Joy and Mary for your replies and suggestions. The information has come from a state librarian in South Australia. As she used the word 'is' in an email, I assumed the property may still be owned by direct descendants. This library holds a copy of the original letter. A copy has been ordered and may reveal more details. Joy, an advertisment in a Fort William paper is a good idea! My UK researcher is working on queries connected with these Sinclairs, and will include the Munro line, but the more I can find, the less she has to do. Thanks again, John.
