Grahamm-- As far as I know, no one any longer believes in this rather misguided theory. Lumiansky and Mills, the editors of EETS Chester, and I all agree that the extant texts are 16th c. the whole notion that Chester comes from some French original is curious to say the least. On the one hand, those medievalists who searched for origins always found them in French texts even when the latter were "lost," the implication being that French was always better. But there is a twist in the discussion of Chester because the Chester plays, supposedly having originated in French dramas, were always described as the most primitive and dull (for which, read, non-literary). There is a kind of conflict of desire in this scholarly stance. My advice is not to worry about French sources for the Chester plays. Larry Clopper
