Robert Trail (1642-1716) was born in Elie in Fifeshire and attended Edinburgh University. His father Robert (1603–1678) was a zealous Covenanter and at one time minster of Grey Friar's Church, Edinburgh.
In 1670 Robert Jr. was ordained as a presbyterian in London and went to serve a congregation in Cranbrook, Kent. He published a 'letter' in 1692 entitled 'A Vindication of the protestant Doctrine Concerning Justification and of its Preachers and Professors form the Unjust Charge of Antinominianism'. This was occasioned by the publication of the works of Tobias Crisp.
On a preaching visit back in Scotland he was arrested for refusing to deny the field coventicles and was put into prison on Bass Rock. he returned to Cranbrook. He then moved to London where he served in an Independent congregation.
His Works was republished by the Banner of Truth in 1975.
