There are many articles in the Journal Archive about the history of Thriplow but an excellent place to start is the special Millennium Edition from 2000, volume 8.3.
Another super overview is given in the Pictorial History of Thriplow.
You can read about the history of St George’s Church (which wasn’t always called that) and about non-conformity in the village.
You might be surprised by the number of manors in the village. You can read about all of them here.
Thriplow was at one time very well-endowed with public houses. You can read about the history of all five(!) of them here.
Another surprise might be that there have been at least three schools in Thriplow. You can read about them here.
