Grenville monument on Lansdowne

I am investigating the Grenville monument on Lansdowne,and have not succeeded in finding either Lord Lansdowne's accounts, or muchmore about the monument's builder, John Harvey, than is reported in Colvin orIson; the only additional info which I have is that the elder Harvey worked atBadminton. Are you aware of anyone in Bath who may know more?

I would be very grateful for your help.
