Grange Family History

English (Yorkshire) and French: topographic name or metonymic occupational name for someone who lived by or worked in a granary, especially the farm manager, from Middle English, Old French grange (from Latin granica ‘granary, barn’ from granum ‘grain’); or a French habitational name from any of the places called with this word, for example in Ardèche and Jura.

Redmonds points out that the English name was interchangeable with Granger. Compare French Degrange and Lagrange.
