Allman
Last name origin: English (frequent in eastern England)
Last name meaning: ethnic name from Norman French aleman ‘German’ or alemayne ‘Germany’ (Late Latin Alemannus and Alemannia, from a Germanic tribal name that probably originally meant ‘all the men’). In some cases the surname may be from the region of Normandy known as Allemagne (south of Caen), probably named as a Germanic-speaking enclave in a Celtic area in Roman times. In North America, the form Allman has probably absorbed some cases of cognates from other languages, in particular Spanish Aleman and French Alleman.
