Hello Tom,
The book was republished by Kessinger Publishing and I bought a copy as I have been trying to find out more about George Elder who was killed in the street in the Tranent Massacre. Unfortunately all sources I have looked at don't give any more information other than he was "of Tranent". My 3xggf was George Elder Montgomery born 10 Nov 1797. His parents were David Montgomery and Christian Elder daughter of George Elder and Jean Steele. Christian also had a brother George(born 1777, died 1836 aged 59). Unfortunately I am unable to find a death for Christian's father and to add to the mix, there are 2 x George Elder born 1762 in Prestonpans and 1769 in Haddington. It may be that 1762 George moved to Tranent or that it was Christian's father who was killed. So happy hunting!
By the way, I am a few years younger than you are - 1952. Left Tranent 1972.
