Fail Family History
Fail Name Meaning
Scottish: reduced form of McPhail. Black suggests that it may also be a habitational name from Fail in Ayrshire. Northern English (Scottish Borders): Reaney has it as a nickname from Old French faille ‘erring’ or ‘failure’, but a more probable source is the southern Scots dialect adjective fail, meaning ‘frail’ or ‘weak’. Altered spelling of French Faile. Altered spelling of German Föhl, Fehl, variants of Feil 2.
