This site aims to transcribe in its entirety the "Scots Peerage Founded on Wood's Edition of Sir Robert Douglas's Peerage of Scotland" by Sir James Balfour Paul, published originally in 9 volumes between 1904 and 1914 at Edinburgh.  There is no reason other than that the site owner finds therapeutic benefit in endless typing.

Although generally sound, the work contains some errors; caution is advised when using it.
