Have you contacted the "Association des Familles Nau" ? They may have information that may be of help! They have been researching the Nau, Naud, Neau, Nault, Neault, No family family for a long time and have a book publised with over 4000 names! Their web address is www.nau.orgthey don't seem to have an e-mail addressbut they do have a fax number. All that info is available on the web site. The book has a listing for Francois Nault married to Marcelline Delisle but they haven't tied it to our family yet, however i have heard that they have volume 2 coming out soon!Good Luck and i hope we turn out to be cousins!
