Johnston Of Wester Milton

A Memory of Wester Milton.

I am in possession of my Great (great?) Grandfather, James Johnston, who wrote a family tree and called it ‘The Johnston’s of Wester Milton. We also use the crest of the winged spur and the the family motto of Nun Quam Non Paratus….(maybe the nun and non are the other way around)! I think we are an off shoot of the Johnstones of Annandale as this tree has the story of 2 brothers sleeping on the Souter hills and a copy of the act of parliament (Charles II) restoring the family name. Any info or help is gratefully required.
