I fully agree with Silvanus that the parish records have not been falsified. For my paternal family I can go back to 1470. The Demolders always lived in the same region in West-Flanders, and I think that, in Flanders, 1450 is about the furthest you can reach with parish registers, if you have luck, because for the majority of parishes ancient registers have been destroyed in the course of time. I am sure that also after 1500 political and religious history have been falsified, but within the frame of a continued civilization. Family histories in my country are one of the reasons why until now I do not accept theories about world catastropes with impact in Western Europe after 1450.
