I m still not sure what you were after when you asked for an annotation or perhaps a new page regarding the origin of Sion but I guess you were wanting a link to the word Zion I assume that the Annemasse hill like many others was named after the Jerusalem hill but since I have no evidence of that I just added a sentence about the origin of the name and the fact that the use of S rather than Z has no special significance it s just the normal way of spelling Zion in French as emphasised in earlier organisations such as the Congregation de Notre Dame de Sion
