The Falconer tartan has the same sett as the Keith tartan, and it was noted by Jack Dalgety in 1963 that, "[t]his sett is the same as Keith, Austin, and Marshall and derives from Lord Falconer who took over the entailed lands of the Keith, Earl Marischal in the early 1800's. There is a family Keith-Falconer who wear this tartan".
