March is Women's History Month and in this week’s episode we mark the contribution of three Scottish women of substance.

Mary Slessor left behind her work in the jute mills of Dundee to travel as a missionary to Nigeria where she did much to advance the rights of women and children. Catherine Herbert, Countess of Dunmore was born at the other end of the social scale and is credited with bringing Harris Tweed to the attention of the world. But were her motives entirely altruistic? Susan’s great grandmother Catherine Scott Morton has no great entries in the history books but was a trail blazer during the war and in local politics post World War Two and her efforts to improve conditions for her constituents were recognised in the award of an OBE.
