Very doubtful they were factual events. Of course, 'blood libel' is an extant phenomenon and there are several cases where it was claimed. But when you examine them in context you can't conclude it was anything but a myth born from ignorance. Though I can believe the first case had some factual basis (I.E. A Jew did kill a Christian child) many others were just made up from whole cloth.
