Mōri Terumoto
The head of the Mōri at that time, Mōri Takamoto, was assisted by the Shōgun Ashikaga Yoshiteru, which led to a peace treaty between the clans. To secure peace, Sōrin proposed that his daughter marry Takamoto's son, Mōri Terumoto. It is not clear, however, if this offer was ever followed through.
