For me personally, GMS's lineage is totally unimportant. I really don't care where he learned the stuff, as long as it works (of which I'm firmly convinced). In fact, I'd be far more skeptical of something which has been passed down unchanged for generations, than of something which has been redesigned for the modern era by a practical, scientific mind. If GMS did, indeed, make up his lineage, it's no more than what many others have done, and since he was marketing a good product, no harm has been done thereby. But I prefer to consider him innocent until proven guilty, and I haven't seen any conclusive proof either way.
Having said that, I can theorize.
GMS said that Fu Yen is actually pronounced "Ho Yen". We've also heard that GMS was taught by the same master as Ark Yuey Wong (AYW) was. If you do some research, you will come up with the following:
GMS was taught the Moh style by Ho Yen.
AYW was taught the Mok style by Ho Yeng.
Coincidence? Let's look further.
Both the Moh and the Mok systems were named after the master who created them (not uncommon).
Both GMS and AYW were teaching the Five Animal Style (Tiger, Dragon, Crane, Leopard, Snake) and Hung.
The trademark of AYW's system is "maximum power and efficiency with the least amount of exertion" (source:
www.shenmartialarts.com/NgGaKuenIKFArticleSMA.html). Sound familiar? It should, it's the most fundamental concept in GMS's system too.
The differences in what GMS and AYW were teaching can be explained by the fact that AYW had many other masters besides Ho Yeng, and that GMS made many modifications to the style to make it more efficient and practical (same sort of thing as Bruce Lee had done to his style).
AYW ended his studies with Ho Yeng around 1919, and GMS began his in 1935, giving the master plenty of time to meet the Simons and immigrate to Germany. This is only a guess, but perhaps AYW was one of the two other silver sash holders that GMS mentions?
The spelling differences are not in the least surprising, since they appear between different AYW bios as well (Ho Yeng is also referred to as Ho Ark Yeng, Ho Dack Ying, and Back Ying Ho; Mok is also spelled Mawk, Muk, and Mo).
I have a TKF yellow page ad from the early nineties which states that membership includes L.A. (among other cities), even though TKF did not have a studio there. I have heard that the studio belonged to AYW's descendants/successors, and that because of their common lineage, GMS and AYW had some sort of agreement which allowed their students to train in each other's studios. Unfortunately, AYW's studio closed down shortly after, and L.A. was removed from the list of membership cities.
Does any of this prove anything? Not really. It shows a possible, consistent version of history, which links GMS's lineage with AYW's. But some people may argue that GMS may have plagiarized his lineage, or invented it in such a way as to match AYW's. If that was true and we consider that Fu Yen never existed, we would have to conclude that GMS lied under oath. We would be at a loss to explain how he got the knowledge to create such an effective system, or how he would simultaneously spar 5 good black belts from various styles, or how his students got to be so successful in martial arts tournaments, or how he got to referee world-class championships, or how he was able to accomplish his unmatched demonstrations (including the 1270 lb ice break), etc., etc. My point is that it's much easier to believe he was taught by a Shaolin Master, than to try to explain how he got to be that good otherwise. And if he did indeed become one of the best martial artists in North America by learning from a magazine, as some people claim, then that in itself would be his greatest feat!!!
