Mr. Red and LadyJean, I'm a native West Virginian, who lived and worked in Morgantown for several years. Even so, I can get my brain and my tongue confused between Monongalia County and Monongahela River and National Forest. Especially since the Monongahela River runs through Monongalia County.

As is the case in Illinois, Cairo, WV (Ritchie Co.) is pronounced KAYro.

The beautiful valley and ski resort in WV, Canaan Valley, is pronounced can-NAIN.

I live in Mebane, NC. Pronounced MEBB-in. Named after a revolutionary war colonel. On NPR (when running thru credits on, I think, Weekend Addition where some one with that last name was or is an associate producer,) and on genealogy websites, some folks in other parts of the country pronounce it MEE-BANE.
Hurricane, WV is pronounced HUR-ri-cuhn.

As far as I am concerned, and I think any person from the Appalachian mountains or plateau would agree, the correct pronunciation is App-a-LATCH-un or App-a-LATCH-uh. Saying App-a-LAY-shian (or chian) or App-a-LAY-shia is a dead give away that neither you, your parents, nor your grandparents were from there:>)
