Brunache Family History

French: habitational name from Brunache, a lost place in Hautes-Alpes in southeastern France, recorded as Brunacha in the 15th century, or perhaps from (Les) Brunaches, a farm name in the same department.

The placename could be ultimately derived from brun ‘brown’. This surname is rare in France.

In the US, it is (almost exclusively) of Haitian origin.
