The dates are confirmed in Sof Scorpion, page 59. I'll complete the information of the Nanabu family but for the moment I add only the dates.
Dates[]
As the Scorpion were disbanded in 1123 I kept it as the official date for disbanding the family, despite the Daimyo committed sepukku two years later, as indicated in Way of the Wolf pages 4-5. Oni no Pikachu (talk) 16:12, July 15, 2012 (UTC)
