The location of Sarah's birth comes fom census records and seems reasonable since her brother was christened there. But there is no record in the church records for her christening around 1829. However the microfilm of the church records are extremely blurred between 1816 and 1825. If she was a couple of years older than she admitted then it is possible her christening is between those dates. There is certainly at least one child christened to John and Elizabeth between those dates but the name is unreadable.
