Borrowdale Family History
Borrowdale Surname Meaning
from Borrowdale (Cumb) whose name is from Old Scandinavian borgar dalr ‘valley of the fortress’ or elliptically from borgará dalr ‘valley of Fortress River’. The switch from -o- to -a- in the first syllable may have been cemented by association with Barrow on Soar (Leics) right in the heart of this name's modern local distribution.
However, it is evident already in the 15th century in the NW whilst -o- also persists in the E Midlands: Jno
