Much of the information on this page was provided by John Henley, who regularly answers questions on mailing lists about Middlesex parishes and churches.
Here is a list of all the Anglican churches of Clerkenwell, and St Lukes Old Street in 1890/1903. with date founded (and closed where appropriate) where known. The first-named in each group is usually the parent parish to those within it, but the area contained many Liberties and extra-parochial places. Original registers if not still with church are mostly deposited in the London Metropolitan Archives. See the London Generations database. In the list below, the name of the church as it appears in their database is shown (in capitals) followed by the words "in LMA database".
For civil administration most of the parishes founded before 1837 also became civil parishes. The county was Middlesex until 1890, then the new County of London. The liberties, parishes and vestries became part of the Metropolitan Borough of Finsbury in 1900. In 1964 Finsbury M.B. became part of the new London Borough of Islington.
I've tried to comment about their IGI status, but if you go to www.familysearch.org and Browse > Browse Library Catalogue > Placename Search [enter Clerkenwell or Finsbury or St.Luke Old Street] and select the one in Middlesex - it can be picky about the spelling of the placename, if no luck first time try all possible variations] > Church Records and Church Records-Indexes, you will see a list of all the LDS film holdings. Batch numbers are on the archived version of the NZ SoG Hamilton site and IGI Batch Numbers, Middlesex and London, places A to M and IGI Batch Numbers, Middlesex and London, places N to Z provided by Hugh Wallis. Some churches may appear on the BVRI rather than the IGI. If on the IGI or BVRI then the LDS has a film of the registers.[which may not be complete].
