I'd just read a new book on Calamity Jane by Grégory Monro editions 2010 Hoebeke, Paris.ISBN9782-84230-389-1
Intitulé les mémoires de l'Ouest. It is all in french, but may be a version in english exist? Some pages are on Carlotte Burge, and the date of birth of Martha is 1856 not 1852 on wikipedia may be you could do something about that?
Sincerely
Sylvana
