Although now included in the London Boroughs, the county of Middlesex lives on historically. Whether your ancestors came from Bethnal Green or Brentford, Whitechapel or Wapping, take a look here to find their baptism, marriage and burial records. Due to the boundary changes over the years, please also see London, Surrey, Kent, and Essex Parish Registers.
More parish register transcriptions on fiche and/or booklets can be found on the relevant family history society pages.
