Are we moving because we thing the grass is greener?
That was partly it originally. In 1980, I had been divorced a few years, was still in the dumps about it, and was convinced Ronald Reagan would destroy America, and this is from someone whose first vote went to Nixon. But I knew the family roots traced to England before 1776, but didn't learn of Devonshire as the departure point (around 1640) until 5 years ago. It would be interesting to see if I could go back any farther.
I had travel guides, imported road maps, etc., and wasn't sure where I wanted to settle if I moved there, but wanted to be outside of London. In the 80s I was favoring the Midlands.
