In reply to your inquiry there is a family association headed by Daniel De L'Etoile who resides in Quebec, Canada. His e-mail address is ddeletoile@fqm.ca and he is a world of information. We celebrated the 250th anniversary of the marriage of the ancestor Bonaventure de l'Etoile De Italien in the new world three years ago in Quebec, Canada at the Citadel overlooking the Saint Lawrence Seaway. Since the arrival of the ancestor was from a port in Italy the De Italien was perhaps an identifier of where he was from rather then a true family name but that is up for debate in my mind.
