Good day everybody, I’m attempting to analysis the historical past of my 18th-century home in rural Dordogne (Bourg-du-Bost space). It’s a traditional two-storey stone home with blue shutters, straight subsequent to an previous mill. What I’ve already discovered: • The home seems on the Napoleonic cadastral maps (early nineteenth century). • The mill subsequent to it reveals up on the Cassini map (18th century), however there aren’t any homes marked at that location on the Cassini map. • I’ve the acquisition deed from the notaire. What I’m caught on: • The native Mairie has not replied to my e-mail after 3 weeks. • The Dordogne departmental archives advised me they don’t have (or received’t present) data going again additional than a sure date. Does anybody have expertise researching previous properties within the Dordogne? I’d love recommendation on: • How you can get extra possession historical past (earlier house owners, building date, and so on.) • Which notaires or native historians to contact • On-line assets or bodily archives which may assist • Any comparable experiences with 18th-century homes on this area I’ve hooked up: • Picture of the home • Napoleonic cadastre part displaying the property • Géoportail overlay Any steering can be vastly appreciated — thanks!
