Analysis of information sources in references of the Wikipedia article "John Perrot" in English language version.
Mary Berkeley was the mother of the most distinguished man of the name of Perrot, but he had little right to bear the name, for he was the son of King Henry VIII, whom he much resembled in person and character. [...] This was Sir John Perrot.
Sir John Perrot did claim to be the son of Henry VIII, though Henry never formally acknowledged him so. Perrot, born sometime between 1527 and 1530, was the son of Mary Berkely, whose husband Sir Thomas Perrot was a courtier and wealthy landowner. John's physical resemblance to Henry VIII fueled rumours that he was the king's son, a belief that Sir John strongly encouraged. [...] Perrot was lodged in the Tower but Elizabeth was reluctant to have him executed. 'God's death! Will the Queen suffer her brother to be offered up as a sacrifice to the envy of his frisking adversaries?' Perrot exclaimed.
