Blackford is a village in Cumbria close to Gretna.
Blackford means what it says, a black ford or river-crossing. However, unlike other places of the name, it is a mix of Old English and Old Norse: the first element is Old English blǣc "black", while the second element is Old Norse vathr / vaőr , ford, river crossing, which usually occurs as -wath in place-names with this element (e.g. Wath upon Dearne). The name was recorded as Blakiwaith in 1165.
