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
