Posting your question here is a good start. You might also check Facebook. There's at least one, and probably more, Facebooks groups devoted to the GAP/C&O, for example Great Allegheny Passage / C&O Canal Enthusiasts. Also, if you are interested in a particular location, try looking for local historic associations in that area, and reaching out to them. If they don't have "docents" who do that type of presentation on a regular basis they might have someone willing to put together a talk for your group on the history you are interested in.
