Hi Mantis9
"Thank you for your feed back. "
You are most welcome, my friend. 
“You have brought to light yet more variation in the Wong Long story that I was unaware. I had always imagine WL as unwed. According to my lineage, he was an unshaven monk, which I assumed meant he never married. My understanding, or perhaps my misunderstanding, of his position within the Shoalin Temple simply made that leap. Very interesting!”
In Taosit even Buddhist traditions (in China), there are those who are devoted to the religious believe or spiritual life without actually joining the Sangha or whatever insititution. In Taoist case, which Wang Lang was in quite a few version, Doren or Xiaosi as a title would be a big hint that he was but wasn’t a monk per se. It is kind of a paradox that Chinese thought patterns are like. One can still live in the secular world doing the “normal” daily things yet you declair that you are devote to the spirituality until you are ready to live in the monastery. Of interesting note is that 7 stars lineages often protraited him as Buddhist monk of Shaolin Temple. Personally, I am more inclined to believe that he was actually a Taoist (Hau Yin is a Taoist Temple) or his spirituality was more inclined as Taoist. This we can see from Meihua lineage Quanpu (Boxing Manual) that there is an abscence of Buddhist terminology and concepts. But there are lots of Taoist concepts (Ying Yang being the most obvious) including Qigong. There might be some reasons that the 7 Stars lineages pushed for the Shaolin identity. One of which is that Wang Yongshan , who was the Grandmaster of GM Luo Guangyu, was well versed in some Shaolin long fist systems as well. It is believe that he created what are considered to be the “pure” forms of 7 Stars. We have to remember that Taoism in Ching dynasty was regarded kind of lowly by the grass root folks because of supposed “employment” by the Ching Emperor as well.
“If I may inquire, what are your sources? Are they mostly oral in tradition (i.e. related to you by your sifu/other masters.) Or do you have some scholastic sources that I may be able to access with permission?”
Believe it or not most of the materials (written) are provided by forum members here and their school sites plus oral traditions of my style (CCK TCPM). Late Sifu Eric Ishii (7stars), his Kung Fu brothers, his friend Bambooleaf (a member here) and Mantiscave, Sifu Carl Albright (7 Stars). Sifu Ilya Profatilov (TJPM & 6 Harmonies), my good friend Tainan Mantis, My Kung Fu brothers Shaolin Mantis and Taijimantis plus many others have been very helpful in providing great material and info. I am sure you will found the quality of the info on this forum is quite high as well. If there are certain material you are looking for and I have them, I don’t mind sharing with you or anyone. But most of the stuff that I have are TJPM material which may not be what you are looking for. Anyway, I am all for sharing. 
"Also, Is the information given about WL’s father and his teacher found within your branch of PM? The reason that I ask is through browsing the internet and communicating with other 7* players I have never happened across this info. Although, one reason for this may be my historical knowledge of PM is still a bit shallow. "
Yes, it was published in the New Martial Hero Magazine back in the 70s. It is now out of print. My Sigung, GM Chiu Chuk Kai did a series of TJPM Kung Fu for them back then. You can find the translation by me on my site.

To be honest, the history of Praying Mantis (any other martial art for that matter) is like Kurosawa’s film Roshamen. Depending on the involvement of the story tellers, the same tale would have myraid versions. One thing I know for sure is that there are 2 main approaches to this quest for the truth: Creation or Evolution.
“Anyway, thanks again. Your post was very informative.”
You are welcome and I am glad that you enjoy my post. Good luck on your journey.
