The Blewbury citizens are often called Blewbarians

In the English Civil War in the 17th century, the village of Blewsbury, in Oxfordshire, was in no man's land between the forces of King Charles I in Oxford, and the Parliamentarian troops. It is noted that one day a troop of Royalist cavalry arrived at Hall Barn in the village, and demanded lunch. They sat and ate their fill, then not long after they left, a troop of Parliamentarians arrived with the same request, and were served at the same tables as their enemy.

Blewbury Mill on Mill Brook is said to be where blotting paper was discovered.

The almshouse, built circa 1738 in the village of Blewbury, Oxfordshire, was built for the oldest man in the village. The second almshouse was built 100 years later in 1838.
