Aparrently the "by" in Rugby and Corby have Viking origins.And also Brondby in Denmark too.
Rugby was originally "Roche" and the neighbouring district Brownsover before the Vikings invaded in 1000 and it became Rugby.The VIKINGS always named towns they had taken with the ending "by".Corby, and Brondby in Denmark being another.
The "by" at the end of the town name signifies "taken" by the Vikings apparently
Marvellous
