 Shortly after Arthur 's death , the idea of betrothing the now @-@ widowed Catherine to the new heir , Henry , had arisen ; both the King and Isabella were keen on moving forward with the betrothal , and the pope granted a dispensation towards that end . After originally rejecting the idea , Henry announced , after his succession on 22 April 1509 , that he would marry Catherine . The wedding took place on 11 June . Catherine bore Henry six children : three sons died before reaching three months of age , a daughter was stillborn and another lived for only a week . The couple 's only surviving child was Mary I ( b . 1516 ) .
