Although the house of the grandson of Imperial Prince Hisaaki, Shoeki is called 'the Itsutsujinomiya Imperial family' (in the book "Tenryuji Jusho Mokuroku") around 1367, there are no records left indicating that either Fukakusanomiya or Shoeki were given the title of Imperial Prince.
貞治6年（1367年）の頃には久明親王の孫・祥益が「五辻親王家」と呼ばれている（『天竜寺重書目録』）が、深草宮や祥益が親王宣下を受けた記録は残っていない。
