Douglas Richardson's revised editions of his popular books, Plantagenet Ancestry and Magna Carta Ancestry, are to be released in February 2010 according to this newsletter:
It seems like he added quite a bit of new content: Plantagenet Ancestry is now 3 volumes of about 2200 pages and Magna Carta Ancestry is now 4 volumes of about 2450 pages. Both were only 1 volume each in their first editions.
Thank you for that link to the Order of the Crown of Charlemagne newsletter. What a fascinating organisation!
Charlemagne, Emperor Of The West and King Of Franks, had about 10 wives and/or mistresses, and innumerable offspring, so there must be millions of descendants. My database relationship calculator cannot cope with the generation spread, so I have not worked out if I am one of them.
