Where is St Severin D'Estissac?

St Severin is in Aquitaine in south west France.  10 years ago, it had about 70 inhabitants.  I think it has far fewer now.  It's about 40 minutes by car from Bergerac.  It has a church, which is not used very frequently, and a mairie, which is used for parties and is really out of place in such a small hamlet.  There is no shop and no school.  No cafes or restaurants.  Nothing.  It's wonderful!  It is situated on the top of a hill, so there are wonderful views over forests in the distance.  It can be quite spectacular when there are thunderstorms.
