English : habitational name for someone from a place called Elham, in Kent, or a lost place of this name in Crayford, Kent. The first is derived from Old English Ç£l ‘eel’ + hÄm ‘homestead’ or hamm ‘enclosure hemmed in by water’. There is also an Elam Grange in Bingley, West Yorkshire, but the current distribution of the name in the British Isles suggests that it did not contribute significantly to the surname.

English and French : topographic name for someone who lived by a granary, from Middle English, Old French grange (Latin granica ‘granary’, ‘barn’, from granum ‘grain’). In some cases, the surname has arisen from places named with this word, for example in Dorset and West Yorkshire in England, and in Ardèche and Jura in France. The Marquis de Lafayette owned a property named Lagrange, and there used to be a place in VT so named in his honor.
