Sal,

Could you clarify your question? Somehow in amongst all that I did not catch it.
Yes, there are many Hongquan some related some not, but pretty straightforward.

e.g. to some I could see:

Yang Jwingming's things are derived from the Nanjing Guoshu Assoc. (combined from Hebei and Shandong Masters' arts). which then was taken to Taiwan.

The Emei qixing set is from Zhaomen (of the 8 men of Emei)....it was derived from Zhili (Hebei) and Shanxi Martial arts so of course related to Shanxi and Hebei arts.

Shanxi Hongquan is itself a combination of arts.........

etc....
