My brother was asked by one of his high school students about the names of the parshios in the chumash; specifically, who gave each of the parshios their names. I searched the archives and see that RAM had asked this question several years ago (http://www.aishdas.org/avodah/vol13/v13n054.shtml#08) but I don't believe anyone gave an answer. KT, Aryeh
