Thanks for all your help so far! I have noticed some discrepancies in the transcriptions also.
@sarachiesura might be better placed to report how much of an issue this is likely to be. We are limiting our search results to a list of institutions that we trust to create good records but I suppose mistakes do still creep in.
This sounds like a good candidate for reporting via the comments field, which I'll be adding to the projects later today as per this post.
