The document is from 1610 and is featured in a book about the "Baron of Salignac" I think. The ancestor is referred to as a Maistre d'hostel, so what does that exactly mean in context for that time period.
It's the lack of a circumflex that throws you off, I think. It normally would be mâitre d'hôtel: the circumflex signifies there was an "s" there. Literally, it's master of the house, but it today usually means butler, or head waiter. Of course, in 1610, it might be a very nice house, a castle or something big, and the butler would be the manager of many servants- so it could be a very important job.
