Four Middleton Events in Middleton Parish???

Dixie points out that there are only four events in this Parish's entire history with the name Middleton attached! Also, there are only two Pemberton events. A real curiosity - maybe the transcription process is only partially complete there?

I sorted the Pemberton records I have extracted, and the predominant parishes in Lancashire are St Mary the Virgin, St Peter, All Saints, and St Michael. I have having a "Dickins" of a time figuring out just where these are.
