Dear PDCStromberg
I had a look for Earl of Alderton on the National Archives Website search page
Came up with this result
http://www.nationalarchives.gov.uk/a2a/records.aspx?cat=010-...(If this link gets removed then search for "A2" +"National Archives" on the internet).
You can contact the owners of the documents (Cambridgeshire record office - you could look up the address on the internet) and purchase a copy of the papers.
Hope this is of some help otherwise though this is outside the scope of my research.
Good luck.
