[ES,III:444]
[36]. Comte de Melgueil et de Substantion. [ES] has a few earlier generations, but they appear to be uncertain so I shan’t bother to include them. Note that it’s very naughty of me to include any armorial bearings (after all, heraldry hadn’t even been invented then) but I like the visual guides, particularly in the charts, so I put them in anyway. So sue me. Just don’t conclude that I really believe them.
