Sir Clements R. Markham, Richard III: His Life & Character…
“ Richard Plantagenet was born at Fotheringhay Castle on October 2, 1452. He probably passed the first five years of his life there with George and Margaret. The elder sisters, Anne and Elizabeth, were married to 'Lancastrian' noblemen, the Dukes of Exeter and Suffolk, when Richard was still in infancy. His elder brothers, Edward Earl of March and Edmund Earl of Rutland, were separated from him by an interval {4} of ten years, and lived with their tutor Richard Croft at Ludlow or Wigmore. ”
