Sometimes things are mistranscribed, and it's always regarded as best practice to look at original documents for yourself rather than rely on what someone else thinks they say. With marriage registers in particular, it can be helpful to compare the signatures of people with the same name, to see if they might be the same person.
I agree, seeing original documents or getting copies isn't always practical or affordable, but it's an ideal to aim for. Anyway, good luck with the rest of your research, and do post again if you need any help.
