Robert Ferguson was born in Scotland, near Aberdeen and died in London. He may have studied at the University in Aberdeen, but by 1655 he had left Scotland – for good, as it turned out – to live in England. At the Restoration he was parson of a country church in Kent, but being a nonconformist he was expelled from his post upon passage of the Act of Uniformity in 1662. For the next fifteen years he moved about, teaching boys, occasionally preaching, writing on matters of religious doctrine and controversy, and keeping in touch with other dissenting ministers; for some of his activities in the latter vein he was briefly imprisoned.
