Yes, I would also think there would be some sort of a record of either scenario happening.
There does not appear to be any mention or signification of multiple registers in the images on FS, but multiple registers seems to be the best explanation...
I am not sure if the current church in L'ubotin is still part of the original church, but If there were multiple registers that still existed, do you think they would be stored in that church?
Or, is there anyone that could be contacted that might know more about the parish records? Maybe a diocese branch or the church itself?
