Please, visit (and invite to all your contacts to visit) the WebSite: http://www.couttolenc.freeservers.com and the WebSite: http://www.couttolenc.8m.com
This sites are in spanish (the next upgrade maybe will are in english too) but in the first I try to explain the possibility of the same surnames: Cout, Couty, Coutolenc, Couttolenc, Cottolengo, Cotton, etc.
I nedd more information to confirm or to refute this observation, please. Thanks
