John Penry, the Puritan martyr, was born at Cefn-brith in this parish.
After the execution of Greenwood, Barrow and the ex-Puritan Penry (a recent recruit to Separatism), in the spring of 1593, it seemed to some that Separatism was " in effect extinguished."
The pamphlets were printed at a secret press established by John Penry, a Welsh puritan, with the help of the printer Robert Waldegrave, about midsummer 1588, for the issue of puritan literature forbidden by the authorities.
Penry however was not found, and in September issued from Wolston or Haseley The Protestation of Martin Marprelate, the last work of the series, though several of the anti-Martinist pamphlets appeared after this date.
The authorship of the tracts has been attributed to several persons: to Penry himself, who however emphatically denied it and whose acknowledged works have little resemblance in style to those of Martin, to Job Throckmorton, and to Henry Barrow.
