Both have perished this year, all my other clematis are doing well,
(Nelly Moser, President, Dr. Ruppel & Etoile Rose)

Has anyone any suggestions as to the likely cause of death?

Well, it certainly wont be the winter weather ! It might be vine weevil
??

If it was vine weevil wouldn't you expect it to attack the Nelly Moser
that lives next to the newer Montana?

Hybrid clematis are prone to some bacterial and fungal infections,
like most overbred plants. You will probably never find the cause,
and it may strike unpredictably. In my garden, I have at least
one unidentified fungus and one unidentified whatsit that have
killed quite a lot of plants. All you can do is to try again
somewhere else, in the same location some years later or try
something different. And sometimes even just replanting with
an identical plant works.

But, since you have lost two, my advice is to try something else.
