Hello fhoiberg!
You have to add in your http://members.aol.com/marismits/geography.htm, another enclave in the french-spanish border region at the Pyrennees:
The spanish enclave LLIVIA (a municipality) in France, just near Puigcerdà, but completely enmvolved by french territory. This is a curious inheritance of the Treaty of the Pyrennees.
Thanks and congratulation for your initiative!
Yours,
Xavier Muñoz,
Geographer
