Filtness Family History
Filtness Surname Meaning
of uncertain origin. The 16th-century spellings Fylt(he)nes(h) Feltnesh could suggest a nickname ‘fell the ash’ for a woodcutter from Middle English fellen fillen + then (the Middle English accusative form of the definite article) + Middle English esshe.
But in the absence of medieval forms of the surname this is bound to be speculative.
