In 2006, Peter A. Marshall from Lancaster researched and documented the heraldry of Combermere. His full article can now be downloaded as a PDF.
It largely focuses on the display of family heraldry in the Combermere Abbey Library, which he believes is one of the most extensive to be found in a country house. However it also explores the crests and shields to be found upon memorials in local churches.
