Joseph Smith's Lists of Inhabitants were included in the Kirk Session records for Birse. The records should be at the National Archives in Edinburgh and some local archives have on-line access, e.g. the Mitchell Library in Glasgow & Aberdeen city and county archives. A photocopied and indexed volume of the List is in the library of the Aberdeen & North East Scotland FHS.
