Looking at what's been entered in the three censuses, I originally read the place of birth as Inswood (1851), Ionswood (1861) and Ions Wood (1871).
There was a place near Mickley called Hyons Wood I wonder if this was where George hailed from?
Take a look at
http://gis.durham.gov.uk/website/intermap/viewer.htmClick on 'search' at the top of the page.
Then select 'coordinates'. A new page will open
In the bottom two boxes enter 409389 and 560010, and click 'centre map'.
This will open a map based on the current location of Hyonswood (but it's not marked on this map).
Then from the drop-down menu at the bottom of the page select the 1856 - 1865 map.
You can then see Hyons Wood.
You can zoom in and out of the maps by clicking on the '+' and '-' signs at the bottom of the map and then clicking on the relevant part of the map itself.
Hope this might help.
