Cosse Family History

Probably an altered form of Breton Le Cossec: metonymic occupational name for a maker or user of spools derived from kos coss ‘reel spool’; or alternatively a nickname from a homonymous word meaning ‘weevil’. This predominantly LA surname (in this sense or perhaps in the sense 2 below) is also found among African Americans.

French (Cossé): habitational name from Cossé-d'Anjou in Maine-et-Loire, Cossé-en-Champagne, or Cossé-le-Vivien in Mayenne, all of which are named with the Gallo-Roman personal name Cocceius + the locative suffix -acum.

French: from cosse ‘pod’ probably a nickname or perhaps a metonymic occupational name for a grower or seller of peas and similar vegetables. Compare Lacosse.

Dutch and German: variant of Kosse. American (shortened and) altered form of an unidentified Greek surname most likely Costas or some other surname beginning with Cost-.
