Dear Mr Hui,
You're welcome, no problem at all.
With the Xuanhe Rebellion you mean the revolt of Fang La as described in Water Margin?
For as far as I know, only two persons from the 18 family sonnet are historical figures: Han Tong and Huaide (Gao Huaide).
Han Tong was said to have arms which can suddenly grow longer during fights. He was a general guarding the gates of Mulingguan before serving under Zhao Kuangyin. Interestingly, the area he guarded lies in present-day Shandong Province.
Gao Huaide was a famous Northern Song general and also the brother-in-law of Emperor Zhao Kuangyin.
Please correct me if I'm wrong.
Regards,
René
