Pro? Pro? They make their living by engaging in life and death combat against skilled martial artists? I really don't think so! You Live in Australia, not 1870s Canton!
The reason we aren't coming up with any names is because fighters such as Wong Fei Hung, Chan Heung, Lam Sai Wing and Tam Sam beat so many people they didn't bother keeping a record of names and styles.
The fact that Keo Yu Cheong respected Tam Sam enough to allow his students to train with him, and vice versa, suggests that he must have thought that his kung fu was worth something!
Really, this is getting old.

"Weapons are the embodiments of fear,
the wise use them only when they have no choice"
