The contemporary L'Éncyclopedié (ou Dictionnaire raisonné des sciences, des arts et des métiers) says quite a lot about "subsistutions héréditaires", but nothing about any Ebenbürtigkeit requirements. I know it was common in the French nobility to marry bourgeois or recently ennobled heiresses (maybe not as common as in Britain, but far more common than in Germany), but I also suspect that some reactionary nobles like the duc de Saint-Simon would try to stop from beyond the grave his lineage being defiled by commoners. Does anybody know?
And BTW - if anybody knows anything concrete about the details of the Sayn-Wittgenstein-Berleburg testament, especially about who is to inherit (the Sayn-Wittgenstein-Hohenstein line?) if Prince Gustav marries Carina Axelsson, feel free to chime in.
