When I was looking for examples of searching techniques for showing how to use Google I searched for Joseph Platt Lofthouse. I had done this many times before but this time I came up with 4 results I had never seen.
They were from the Archives of the Royal Commission for the Exhibition of 1851.
I had previously found a plan of the 1851 exhibition area that surveyor Joseph Platt Lofthouse had done and been sent a photo of it by the National Library in London.
However these were letters to do with payment for work done. I wrote to the archivist there and asked about visiting the archive when I go to the UK later in the year but she very nicely offered to scan the letters for me and they arrived a few days later along with the new plan. We now had 2 plans prepared by J P Lofthouse. My husband was delighted to see his great grandfather's hand writing and new plan.
