After the death of Hidenori, Sadamasa ISHIKO of a powerful clan in Mino Province invited Keinan Shusen and repaired the buildings in 1632 in order to hold a memorial ceremony on the 50th anniversary of his father's death, and also took one character from the posthumous Buddhist name of his father, 'Tensenshukei Daizenjomon,' and his mother, 'Shoinmyoshun Daishi,' to give the temple the new name of Keishun-in Temple.
秀則死後、美濃の豪族・石河貞政（いしこさだまさ）が寛永9年(1632年)に父の50年忌の追善供養のために桂南守仙（けいなんしゅせん）を請じて建物を整備し、父の法名「天仙守桂大禅定門」,母の法名「裳陰妙春大姉」から２文字をとり桂春院と改めた。
