I’ve just found my Vincent Hawkins of Little Coxwell, Berkshire on the new Post office Appointment Books 1737 – 1969 dataset on www.ancestry.co.uk. He was appointed sub postmaster in 1859. In the 1901 census he was aged 82 and was still working as the sub postmaster and living at the post office. For 40 years he was also the parish clerk and fitted in work as an agricultural labourer in his younger years. Obviously a very industrious fellow.
