Perhaps you should try some spelling variations:
prevost de » prevost des, prevot des, prevost _
de garder » de harder, le garde, de gaer
prost de » post de, trost der, joost de
de gandt » de gand, de grande, de grands

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( prost de garder ) OR ( prevost de gandt )).
• Adding a wildcard symbol may retrieve word variants: (( prost de garder ) or ( prevost de gandt ))*.
