In "Myoshinji-shi," or the chronicle of Myoshin-ji Temple, there is an entry that says that the wife of Nobunaga organized the first year anniversary of Nobunaga's death on July 20, 1583, so it is highly possible that this was 'Azuchi-dono (or Mitsubone)' because it was a Buddhist mass not hosted by Hideyoshi and that the "wife" here would not refer to Kyounin (Onabe no kata).
『妙心寺史』には、天正11年6月2日（1583年）に信長公夫人主催で一周忌を執り行った記事があり、秀吉主催とは別の一周忌法会であるため、興雲院（お鍋の方）とは別人と推測され、「安土殿（または御局）」である可能性が高い。
