*It has been suggested by Dr Michael CRAWFORD in his "Working Pedigree of The Crawfords of Crawfordsburn and their Cadets" that Hugh CRAWFORD of Orangefield was one of their children, but as this is unproven, it has been left as a separate issue and can be explored further by those interested in Orangefield and Tree1e CRAWFORDS OF ORANGEFIELD
