Margaret Ward was a convert according to some sources. Here is her story from the Catholic Encyclopaedia online.
Martyr, born at Congleton, Cheshire; executed at Tyburn, London, 30 Aug., 1588. Nothing is known of her early life except that she was of good family and for a time dwelt in the house of a lady of distinction named Whitall then residing in London. Knowing that William Watson, the priest who wrote the work known as the "Quodlibets", was imprisoned, she obtained permission to visit him. After several visits she disarmed the vigilance of the gaoler and furnished him with a cord whereby he could make his escape. At the appointed time the boatman whom she had engaged to convey the priest down the river refused to carry out his bargain, and in her distress she confided her difficulty to a young man, St. John Roche (or Neele), who undertook to assist her. He provided a boat and exchanged clothes with Watson, who made good his escape. But the clothes betrayed John Roche, and the rope convinced the gaoler that Margaret Ward had been instrumental in the flight of the prisoner. They were both arrested and loaded with irons. St. Robert Southwell wrote to Father Acquaviva, S.J.:
She was flogged and hung up by the wrists, the tips of her toes only touching the ground, for so long atime that she was crippled and paralyzed, but these sufferings greatly strengthened the glorious martyr for her last struggle.
She was tried and condemned at Newgate, her liberty being offered her if she would attend Protestant worship.
Margaret Clitherow's story is well-known. Again, I take the information from the CE and it is now thought that she was pregnant at the time of her martyrdom, which would have made the crime even more heinous:

Anne Line is the last one considered here. She was a convert. Again, let us look at the CE online for her story:
English martyr, d. 27 Feb., 1601. She was the daughter of William Heigham of Dunmow, Essex, a gentleman of means and an ardent Calvinist, and when she and her brother announced their intention of becoming Catholics both were disowned and disinherited. Anne married Roger Line, a convert like herself, and shortly after their marriage he was apprehended for attending Mass. After a brief confinement he was released and permitted to go into exile in Flanders, where he died in 1594. When Father John Gerard established a house of refuge for priests in London, Mrs. Line was placed in charge. After Father Gerard's escape from the Tower in 1597, as the authorities were beginning to suspect her assistance, she removed to another house, which she made a rallying point for neighbouring Catholics. On Candlemas Day, 1601, Father Francis Page, S.J. was about to celebrateMass in her apartments, when priest-catchers broke into the rooms. Father Page quickly unvested, and mingled with the others, but the altar prepared for the ceremony was all the evidence needed for the arrest of Mrs. Line. She was tried at the Old Bailey 26 Feb., 1601, and indicted under the Act of 27 Eliz. for harbouring a priest, though this could not be proved. The next day she was led to the gallows, and bravely proclaiming her faith, achieved the martyrdom for which she had prayed. Her fate was shared by two priests, St. Mark Barkworth, O.S.B., and St. Roger Filcock, S.J., who were executed at the same time.

Roger Filcock had long been Mrs. Line's friend and frequently her confessor. Entering the English College at Reims in 1588, he was sent with the others in 1590 to colonize the seminary of St. Albans at Valladolid, and, after completing his course there, was ordained and sent on the English mission. Father Garnett kept him on probation for two years to try his mettle before admitting him to the Society of Jesus, and finding him zealous and brave, finally allowed him to enter. He was just about to cross to the Continent for his novitiate when he was arrested on suspicion of being a priest and executed after a travesty of a trial.
