After a quick look over I think you have it mainly correct except for:

You thrived with Bolckow, Vaughan and the engine of steam

In Coral, Connaught, Pearl Street too


Bolckow (Henry William Ferdinand) and Vaughan (John) were responsible for the development of the steel industry in Middlesbrough. (Their statues were at opposite ends of the garden in Victoria Square outside of the Town Hall.

My (ancient) transcription shows the 2nd line ending in steam, but I'd like to recheck that before dismissing your steel,
