<<snipped>> There are no other datasets on FMP which are called 'Diocese of .' <<snipped>> Interestingly if you look at the Shropshire PRs, they are referred to as "Shropshire Baptisms" - I guess because they are. Looking at the England & Wales Jurisdictions map of 1851 on http://maps.familysearch.org/#layer at that time the (very roughly) northern part of the county was in the Diocese of Lichfield and the rest in the Diocese of Hereford. What you get on FMP are the two halves of Shropshire, lumped together. Hence Shropshire is the only appropriate name. I presume that the records in FMP have all come from originals at Shropshire Record Office.
