Gary...

There are several sites in Arkansas (rivers, creeks, "bottoms," etc.), that carry the spelling of Fouche. I've heard that it comes from the French trappers who worked this area in the late 1600s up through statehood (1836). I don't know if it has some geographical, botanical, etc., meaning in old French...or might be a surname of one of the French trappers or his party....or what?

Locally, it is pronounced, "Fooosh"...where as my SE Texas (touch of Cajun??) would pronounce it as, "Foh-shay." Is it possible that your "Forishee" might be derived from "Fouche?"

(You ought to see what's been done to DuBose thru the ages...duBosc, Dubosk, duBois, DuBoise, --- proper and traditional way to say it was either (1) the French style, "doo-bwah" or (2)the modern style, "doo-boze." I can only imagine what a 19th century, Anglo-Saxon/Scot-Irish census taker with probably a 3rd "reader" education might have done trying to take "Forishee" from the verbal to the written word!)
