"and was within the historic county of Kent until 1889" is an incorrect statement. The historic county of Kent still exists, it is one of the 92 historic counties of the UK and Lewisham falls within it. There has always been an understanding that the administrative areas created by local government legislation (including that of 1889) are different in kind to the historic counties. This is expressed by the Office for National Statistics (ONS) in its Index of Place Names in Great Britain and is recognised by government. Lewisham did not cease being part of the historic county of Kent in 1889. There is a confusion here between historic county and local government entity, confusingly also referred to as 'county'. Perhaps a more accurate statement would be "Lewisham is in the historic county of Kent and falls within Greater London for local government purposes"?
