Given John and Mary name two of their children William and Ann, it's possible the parents are the family you are looking at and given naming patterns were often used. I would have expected a John or/and a Elizabeth would have featured if the Rampton birth was correct.
Remember these are only transcriptions, the parish registers may hold the baptism you need. One of William and Anns children's surname was transcribed as AMSWELL in Stapleford.
