Allman Family History

English: ethnic name from Old French aleman(d) ‘German’ or alemayne meaning ‘from Germany’ which was called Almeyne in the 14th century (from Late Latin Alemannia from an ancient Germanic tribal name that probably originally meant ‘all the men’; see Allemann). In some cases the surname may be from the region of Normandy known as Allemagne (south of Caen) probably named as an ancient Germanic-speaking enclave in a Celtic area in Roman times.

English: variant of Oldman. Americanized form of German Allmann or Ahlmann (see Ahlman).
