The inscription on the mug is somewhat misleading, suggesting that William Moxon 1802-1902 was celebrating his own centenary. However this William Moxon, son of William Moxon and Elizabeth Senior was born about 1829 and died in 1904. His grandfather Samuel Moxon, head of family tree MX20 had established the farm. According to descendants writing in various Moxon Magazines, the family ran a carpentry business.
More information about the farm, the family and the memorabilia can be found in Moxon Magazines issues number 17 (1996), 45 and 46 (2010).
