To those who were following my search for detail about Alexander Purdie ( all three) , Mary Morrison and John Purdie and Rockburn cottage.. I have found an item in the Edinburgh Gazette about the sequestration of Alexander 1820 Purdie`s estate which tells me the hotel that Alexander ran was in Ardrishaig , so I figure Rockburn cottage was also. Mary Morrison was already deceased by 1854 as Alexander 1847 and John 1849 had to have adult representatives in court as they were the only beneficiaries ( as 5 and 7 year olds) of Alexander`s estate.
