There is much debate over the true representation of the Mar District tartan. In order that the matter should be settled and the design be ''known and recognised as the proper tartan of the Tribe of Mar", the Rt Hon Margaret of Mar, Countess of Mar, made a petition to the Lord Lyon to record this sett. The designer is unknown and the date is possibly pre 1850. Frank Adam called the sett Skene, and said it came from the Duke of Fife whose ancestors owned Mar Lodge. Both Skenes and Robertsons lived in the Mar District. Lord Lyon's Tartan Committee agenda for 14th March 1978 records the sett as "R2 K3 G45 K3 Y2 " On the Tribe of Mar webste however this is not regarded as a District tartan but is shown alongside the Red Mar, both of which seem to be regarded as clan tartans.
