Another myth debunked is "Until about 1900, 99.9% of people never travelled more than 10 miles or so from their birthplace". While many families in rural areas in the 1700s and 1800s stayed local, many of them did travel around the country for work, or move to cities, and even moved from various villages in the county to another.
I grew up in Rollesby, Norfolk, to Essex parents but both had some Norfolk blood, and one ancestor from Norwich, which, as the crow flies is only about 11 or 12 miles from Rollesby. So it may means several people whose family had mainly lived in Rollesby were likely distant relatives, as the 1851, 1861, 1871, 1881 etc Rollesby censuses lists some residents born nearer to Norwich such as Wroxham, Brundall, Blofield or Acle, living in Rollesby. And my Norwich ancestors had some ancestors from near Brundall, Wroxham, Ludham etc.
The most westerly Flegg area village is Thurne and Clippesby which, as the crow flies is just 8 miles from the Carrow Road football ground area of Norwich. So more or less the same area ATEOTD, especially when you know people travelled thousands of miles/were sent thousands of miles to live and work in Australia, US, Canada, NZ, India, South Africa, South America etc.
