The recently published journal (yes, 2013) of the Scottish Records Association has a detailed article on material which is discussed in the 'Appendix' of Thomas Sinclair's The Gunns and part of which I have called the 1868 and 1870 trees of Aeneas Gunn of Edinburgh.

The provenance of the documents is beyond question as the material is held by the family of Aeneas Gunn of Edinburgh.
