I am sorry but I have no information on the Hunstein family. Are you subribed to the Alsace mailing lists, for example at www.rootsweb.com and have you checked with the National Archives in Canada? They do have a website. I don't have the link at hand right now but it's listed on my website. Click on Links and scroll down to Canada. If you need any more help please don't hesistate to contact me again.
