I happen to have information on your corsican relatives, which I discovered as I searched for my own and contacts in Corsica that can help you in your research. I have been in touch with various members of the Siscos from Lares and I'm friends with a few on facebook. I was hoping to have someone from this branch of the Siscos, with whom to share my findings and other information. Are you on facebook and do you have an e-mail address you can share? My e-mail is: eve439@live.com
