(My great-great grandfather William Ezard was born in 1812, in a small village in the East Riding.)
CD: The British 19th Century Surname Atlas, ver 1.10, www.archersoftware.co.uk , 2011.
(Note: Version 1.2 is now available.)
Here you can find the historical distribution of any of the 400,000+ surnames that appeared in the 1881 census, and all the forenames too. You can generate a map for an individual name and also a ‘quartered’ map for four names of your choice. You can see examples in the Name/Distribution page on this blog.
An atlas of old county maps is also very helpful. I am using Thomas Moule’s The County Maps of Old England, originally published in 1830 as The English Counties Delineated. But my copy is a ‘coffee table’ reprint, Studio Editions Ltd 1990. These maps show wapentakes and hundreds and give a good idea of the ‘spaciousness’ of a county, which has been lost in modern times. I came across this copy in a charity shop.
