Is the surname Allen english?
I found this for you. Surname: Allen This distinguished surname with more than fifty heraldic Coats of Arms granted to nameholders, and having several notable entries in the British ‘Dictionary of National Biography’, is equally widespread in England, Scotland and Ireland. It derives from the Gaelic and Breton personal name of the pre-Christian era ‘Ailin’ which loosely translates as ‘Little rock, although it may also mean ‘harmony’. The first recorded name bearer was ‘Alawn’, a legendary poet of the fifth century a.d., reputed to be one of the three foremost musicians of the period. From early times the spelling form has varied considerably not least in the Celtic countries where it has ranged from Eilian to Alwyn and Alleyne. The Bretons, who were originally British settlers in France, returned as invaders with William, Duke of Normandy, otherwise known as ‘The Conqueror’ in 1066, and in so doing it is claimed, re-introduced the name into England. Certainly ‘Alanus’ without a surname
