I sent screen shots of the duplicate burial records to Derbyshire FHS. They checked the original images and confirmed there were no Wardle or Hallam burials in Scropton. The Stoney Middleton ones were correct though. They think that the records were possibly uploaded for Scropton by mistake and that someone had pointed out the error. They think that the records were then entered for Stoney Middleton, but that the incorrect Scropton records weren’t taken down.
When I came to make screen shots of the duplicate baptisms for them, I found that the Shirland records had already been removed, presumably somebody else had queried those.
