I'm (nominally) admin for the Rootsweb mailing list
LAURION-L@rootsweb.com, which is the primary spelling of the surname, although there are a few other variations as well (LORILLON, DORION, LARION, LORIAN). To join LAURION-L, send an e-mail to <
LAURION-L-request@rootsweb.com > with the single word 'subscribe' in the message subject and body. I also maintain a list (which combines two extremely-low volume surnames) at Yahoo. To subscribe there, send a blank e-mail to <
LAURION-GADDA-subscribe@yahoogroups.com >. Do join; both of these lists run about 2-3 messages/year(!), so they're not likely to be a burden on your e-mail system :) . Of greater interest would be the website kept by Nathalie Laurion at <
http://nlaurion.club.fr/english/indexenglish.htm >.
