William Criddle
William Criddle was born in 1813 in Plymouth. Before coming to work for the FR as a driver in 1865 he was already (1861) a locomotive driver living in Bangor. In 1871 he was living back in Bangor again as a loco driver but not for the FR.
He had 2 sons, Richard and Thomas, who both appear to have worked for the FR as a smith and a cleaner for a while.
