Born in Carlisle, Murchie moved to Manchester with his family while young, and became a carpenter.
Known for his wide reading on trade and social matters, he became active in the Amalgamated Society of Carpenters and Joiners (ASC&J), and quickly rose in importance.
In 1881, aged only 31, he was elected to succeed John D. Prior as general secretary.
The ASC&J held annual elections, and Murchie was re-elected each year.
[1] In 1888, Murchie attended the TUC, at which he spoke, and was again re-elected to the Parliamentary Committee.
