Casterton is a small village and civil parish close to Kirkby Lonsdale on the River Lune in the south east corner of Cumbria, England.

It was enlarged in 1865 and restored in 1891, and is at present run as part of the 'Rainbow Parish' based in Kirkby Lonsdale, a combination of eight, originally seven, churches.

He was living at 10 Abbotsgate, just off Mitchelgate, in Kirkby Lonsdale, at the time -- his daughter Ruth was a pupil at the Queen Elizabeth School.

Once a week he, his American wife Jane and friends would form a team in the pub quiz at the Pheasant Inn at nearby Casterton.
