It wasn't quite fair of me to do this. My DF was in the army. In my childhood I lived in London, Carlisle, South Yorkshire, Hong Kong (American English), Singapore and Berkshire. As an adult: Newcastle, London, Berkshire
The test showed my vocabulary as coming from a broad sweep of territory from Norfolk to Surrey with concentrations in Norfolk, Cambridge and Essex-London-Surrey. Where the bias towards East Anglia/home counties, north of the Thames comes from I have no idea. No family connections there at all. My parents were both brought up in South London
There was a soft haze of colour over the Northeast, where I went to University and a lighter haze over South Wales and Somerset, another area I have no connections with.
Interestingly nothing marked in Ireland despite having two Irish grandparents, one on each side.
