NORTHERN Hung Gar?

I'm aware of differing lineages of southern shaolin hung gar kuen, but I've been reading up on the hung kuen lineage I'm part of, and it mentions Lam Sai Wing, Wong Fei Hung etc, how this school's Hung Kuen was developed in Malaysian, but then it mentions the system comes from a Northern Temple, even though it includes the Taming the Tiger, Iron Wire and Five Animals, which to my knowledge is a Southern thing. Have I gotten confused or does a Northern HK exist outside of the Southern branches?
