January - March 1508 (yeah, I know, I haven’t been doing this, but now’s as good a time as any)
The queen went into confinement right after the Feast of the Epiphany, among her ladies was Viscountess Rochford, Elizabeth Boleyn, whose son with Prince Henry was being raise with her children at the Boleyn home. Elizabeth had apologized to the queen, but since her husband had been willing to give the boy his name, he had been made Viscount Rochford for his courtesy to the king. (Which is what King Arthur considered it.) On the first of February, Catalina gave birth to another daughter, Elizabeth, so named for the king’s beloved mother. The child was almost immediately called Bitsy, because she was so small and initially not expected to live long. But she survived, and the nickname stuck within the family.
The betrothal contract between Prince Henry, Duke of York and Eleanor of Austria, niece of Catalina by her sister Joanna, was formalized at the end of January. The pope had granted a dispensation for the marriage in England, but declined the same for her Uncle (Manuel I of Portugal), which gave England the edge it needed to make the union possible. Ferdinand, Catalina’s father, made her Duchess of Cadiz, with the revenues (along with a grant from him) and the title for her husband, as the dowry. Arthur, with Catalina’s urging, accepted the match after the properties for revenues were increased and the terms were settled: only the children of Eleanor would be eligible to inherit, but Henry could retain the title if she died and there were no children to assume the title. Henry, true to his word, proclaimed that the Pope could not have a match so pleasing to his person.
Eleanor would arrive with her ladies (Catalina had explained that the English household had no provision for a male household, unlike the Spanish) in the spring of 1508, giving her time to learn English and English ways before her marriage. The wedding was set for the Christmas of 1510, after the bride had reached her 12th birthday (November), giving both time to become acquainted.
