First James V was not the first choice for the daughters of Francis (and he was offered Mary of Bourbon in OTL), second Elisabeth will be the only princess available for him in 1517, at the treaty of Rouen, reason for which is likely who James will be directly engaged to her there (and not to a not specified French princess, possibly a daughter of Francis if the King would have one available for him as OTL), third Elisabeth herself is likely to be the most attractive French princess for James as she would bring to him her own claim to the English crown.
