Hi Laura,
I see that as well as your interest in the Chalmer family you also have an interest in the Gaskells.
I have a letter written in Liverpool in 1797 by Alicia Gaskell to her friend a Mrs Weanwright.
In the letter Alicia mentions Mr Chalmer, who I believe she was staying with.
I can let you have a transcription of the letter if it is of any interest.
