 This was backed by Michael himself, who in 1594 referred to Petru as "My Highness' brother".However, at least one account in English diplomatic records disputes Petru's background, alleging that, rather than Pătrașcu's son, he was a Greek from Morea.Petru, who took the Wallachian throne in July 1583, had at least three sons, of whom Marcu is the best known.
