Mystery Chairs - Please help to identify

I dont know much about these chairs or the table except that it belonged to my great grandparents and has been in our family for a while. They came from western europe. I have no idea where the chairs originated or who manufactured them but they are beautiful.

The chairs are made from wood (no leather on them). That is all that I know. Set of 7 chairs and a table. Any information on them would be fantastic!

Please share your comments or information. First time posting these pictures and asking about them. Only a handful of people have actually laid eyes on these for the past 30yrs as they have been stored in a private beach home.
