Robert Ker (the younger) known as Robert Ker of Kersland was a Covenanter. He sympathised with the insurgents who fought at Rullion Green and consequently was declared a rebel and his lands became forfeit. He escaped to Holland but following his wife home on business he was captured while visiting her in her sick-bed in Edinburgh. He spent many years in various jails. He is remembered by Christian historians and biographers such as Wodrow and Howie as one who suffered for the Presbyterian cause in Scotland.
