The lords of Faucigny hold the valley of the Arve and the Giffre between Geneva and Mont Blanc.
On 1 January 1200 the lord is William, not his brother Aymon II, who will succeed him at the end of 1202.

Threats
- Geneva's claims

Places of note

Where the sources disagree
- The assignment names Aymon II for Faucigny; fr.wikipedia makes his elder brother William lord from about 1197 to late 1202, so Aymon II is not yet lord on 1 January 1200.
Evidence: One modern account; dates approximate.
On the map: Core only; the upper Arve (Sallanches, Chamonix) is not drawn.
