  ==Jean-Baptiste Chaigneau== Hi Angus! For my work on Jean-Baptiste Chaigneau, I am planning to use as a complement one of my books: Un Mandarin breton au service du roi de Cochinchine, by André Salles, Editions Les Portes du Large 2006 ISBN 291461201X. Although a re-edition of research made in the 1920s, the book has a lot of interesting details on Chaigneau. Could you give me your comments? Cheers
