Hi Vicki. Having re-read some of my contributions on this subject I may have caused some confusion by referring to Parishes as they existed at different periods. At risk of teaching you to suck eggs, may I explain that the original pre Norman parish for this area was St Andrew Holborn, which stretched over a huge area, much of it countryside. As the population grew, new parishes were created within the original St Andrews area. Thus it is important when looking at maps, parish records and early census documents, etc, to choose the right one depending on the date being searched. Ignoring very early divisions such as St Giles in the Fields 1547, the first new parish was St George the Martyr, initially as a 'Chapel of Ease' from St Andrews and subsequently (1763?) as a full parish in its own right, mostly covering Queen Square, Red Lion Square and adjacent roads. By 1875 St George the Martyr had become too small and was further split to form St St John the Evangelist, Red Lion Square.
Little happened to the rest of St Andrews Holborn parish boundaries for a further 50+ years, when St Peter Saffron Hill was formed in 1832, Holy Trinity 1839 and, lastly, St Alban (Ben's parish!) in 1863, ie after the 1841 and 1851 census. Sadly, changes to the registration Districts after 1837 simply further add to our headache of reconciling records that we unearth.
