Northumbria/Northumberland
I have always thought that the name of this area could have been coined from the Roman invasion when some of the troops may have come from Umbria in Italy & saw the area as being similar to their home surroundings & so called it North Umbria, but I have never actually found anything to support this theory. Does any A/Ber have thoughts about this ?
The English river Humber and the Italian region Umbria are two different places whose names have completely different etymologies. It's coincidence at best...
