Architecture and Genealogy in France

This really interesting website is all about the late 19th and early 20th century villas in the Ubaye valley in France. They were built by families who had become wealthy after emigrating to New Orleans and Latin America. My brother says that these are the McMansions of the turn-of-the-century but I think they're beautiful. Among those who emigrated to New Orleans was Marius Jaubert, my great-great grandafther. Les Charmettes (shown in the phot here), a lovely art nouveau villa, was built by a member of the Jaubert family and I am also related to many of the other families mentioned on the site (Signoret, Reyne, Auddifred)
