I have worked a lot with French Canadian ancestors and have encountered this site numerous times: http://www.nosorigines.qc.ca
My impression of the site is that it is much like WikiTree. It has a family tree and you can click on different people to see their data. I thought that, like WikiTree, this site was user-generated, meaning that anyone could go in and add information. This would mean that it is NOT suitable as the only source for information on a WikiTree profile (just like how you shouldn't use Ancestry.com member trees, or any other user-submitted family trees, as your only source; instead, you find where the information came from and cite that).
Recently, though, I have encountered a whole lot of profiles where a link to this site is the only source (it appears as though someone was following along and copying the names and relationships given on the site). I was especially troubled by one (Moisan-61) because I have looked at original records in the Drouin Collection and I am certain that the information on nosorigines is incorrect. (You can see my comment on the profile.)
I do not see any sources at all listed on the nosorigines site. There appears to be an icon that you can click on which says "Notes, Information" but when I click on it it asks me to register for the site, which should not be necessary if I just want to know what the source of the information is!
Am I missing something? Or am I correct in thinking that this site has user-generated trees and anything with this site as the only source should be marked "Unsourced" until a primary source is found and cited?
