John Hodgson, in a memoir published in 1831, held that Horsley was born in 1685, at
Pinkie House, in the parish of
Inveresk,
Midlothian, and that his father was a Northumberland
nonconformist, who had migrated to
Scotland, but returned to England soon after the
Glorious Revolution of 1688. John Hodgson Hinde, in the
Archaeologia Aeliana of February 1865, held that he was a native of
Newcastle-on-Tyne, the son of Charles Horsley, a member of the Tailors' Company of the town. David Boyd Haycock writing in the
Oxford Dictionary of National Biography comments that none of the suggestions made for Horsley's background is verifiable. He was educated at the
Royal Grammar School, Newcastle and at
Edinburgh University, where he graduated
MA on 29 April 1701. There is evidence that he "was settled in
Morpeth as a
Presbyterian minister as early as 1709." Hodgson, however, thought that up to 1721, at which time he was residing at
Widdrington, "he had not received ordination, but preached as a licentiate." ==Educator==
