Tuhia he tomokanga mo tenei pene - I whanau a Margaret i Farleigh Hungerford Castle i Somerset, te tamahine anake o George Plantagenet, 1st Duke o Clarence, me tana wahine a Isabel Neville, ko ia te tamahine matua a Richard Neville, 16th Earl o Warwick, me tana wahine a Anne de Beauchamp, 16th Countess o Warwick. I mate tana tupuna whaea i te whawhai ki tana matua keke, a Edward IV, i te Pakanga o Barnet
He aha? Ko tana papa, he Duke o Clarence, i hangaia ko Earl o Salisbury me Warwick. I kii a Edward IV ko te taina o Margaret a Edward kia mohiotia ko Earl o Warwick hei taitara whakaute, engari kaore ano kia hangaia he rangatira mo ia. I whai mana a Margaret ki te Earldom o Warwick, engari i ngaro te earldom i runga i te taenga mai o tana tuakana a Edward.
