Page 1 of the Ipswich Journal, 3 Jun 1854 carries two adverts referring to "Hoo Hall. One relates to the "Grand Courts Baron of Sir Edward Clarence Kerrison" at Oakley, the other to supplying improved turnip manure and mentions the Ellis Lethers Glede at Hoo/Plomesgate (already mentioned). Oakley and Hoo are about 19 miles apart and the adverts may be referring to the same property. Just want to confirm you are chasing the Hoo/Plomesgate property already well identified by Maddy?
I cannot post images of the newspaper adverts (status of post does not cater for attachments).
