Ashfield came from a Buckinghamshire family and was a pupil of John Michael Wright (1617–94). He worked both in oil and in pastel; according to Robert Edmund Graves, he excelled most in the latter. Vertue mentions a neatly painted head by him of Sir John Bennett (afterwards Lord Ossulston). He also appears to have been also a copyist, for there are portraits of Frances, Countess of Warwick, and of Mary, Lady Herbert (later Duchess of Richmond and Lennox), after Van Dyck, which Graves notes are finished with extreme delicacy.
Graves opines that his crayon drawings were highly finished, and characterised by the harmonious blending of the tints, of which he multiplied the number and variety, black and white only having hitherto chiefly been employed, the paper forming the middle tint.
