9th generation Sekiō Sōshitsu (1746-1801) 石翁 宗室
Started using hte nam Genshitsu at age 11 or 12. This is know from the 100th memorial events of Sôtans passing. In which Genshitsu arranged flowers for most of the 100 events.
In 1760 he did a chaji at the imperial palace by request of the imperial temple Hôkyôji.
On New Year’s DAy in 1788 a fire broke out east of the river. Fortunately Omotesenke and Urasenke had time enough to save their precious utensils, but it would become Genshitsu’s life work to rebuild the burnt buildings and the estate.
