Martín Muñoz
Martín Muñoz de Montemayor or Martín Muñoz de Ribadouro (PT: Martim Moniz de Ribadouro) (before 1080 - after 1111) was a medieval noble from the County of Portugal who, through marriage, became the son-in-law of the famous ''alvazil'' Sisnando Davides. Sisnando appointed him as alvazil, and after his death, Martín became the new Count of Coimbra. He was later deposed and nominated ''Governor of Arouca'', eventually moving to the courts of El Cid and Peter I of Aragon.
