Doona, I haven't ordered any acts or certificates (birth, death) since the QC government took them over.I have heard, though, that there are many mistakes & not much info is included except name of parents, etc. the usual. Since the advent of the Canadian & QC law re: right to privacy, info is more difficult to get. Even the churches were advised by the bishops that they should not give out personal information such as birth, death & marriage info to anyone other than direct family & that upon a written request.Also, you have to pay for acts & certificates, which are long in coming...sometimes months. So, your best bet is to find out where your ancestor was married so that we can search the church registries that are already published. If you know where she was born, that would give us a hint. Some registries include the parent's name even though the child was illegitimate; others don't, depends upon the parish policy at the time. I own several QC Roman Catholic marriage registries (a few baptism ones also); therefore, if you have an idea of where to start to look, I'll check them out for you. Good luck in your search.
