Dear Sir,
I received your favor of the 10th inst with a Ck for Seventeen pounds which is payed to your credit – there was no occasion to apologise about a short delay in sending it – any time that suits yourself will suit me.
I am glad to hear Mrs Grey has accomplished her trip to Holy Island and sincerely hope she will receive much benefit from the change of air etc - it is to be regreted your matters would not allow you to give a little of your time to join the party. I would indeed have been most happy to avail myself of your kind invitation but my very precarious state of heath and great weakness prevents me leaving my own fireside or a change of bed. I have not done so since I visited you & and Mr C Howey for years – excepting a day and a half on my visit to your sister at Charlton Hall as a Bride in Sept -1848 -nor is it likely I shall be enabled to do so. I hope however Mrs G. Grey will be able to pay me a quiet visit whenever it is convenient – that we may not quite forget each other – it will afford me great pleasure. I write with great difficulty and am as usual tired and weary – and with kind love to your good lady and yourself must conclude this scrawl. I am Dear Sir Yours most truly

Letter in Berwick archives. (NRO 496 - Grey of Milfield)
This is possibly the uncle Joseph Hardy who bought Josephine Butler her piano. A. S. G. Butler in his book about Josephine, records that her rich uncle paid 200 guineas for it and that it had won first prize at the Great Exhibition. (Portrait of Josephine Butler, 1954, p. 42) However the above Joseph Hardy died in 1851. He appears on the 1841 census at Narrowgate, Alnwick, aged 60, occupation Bank Agent, with two female servants: Jane Vardy aged 40 and Jemina Lockey 15, and the tax on his will is listed in 1851, with John Grey, Dilston as his executor.
