Across the world, Sannier (Sannier 
) is a rare principally feminine, but very seldom male forename. The given name Sannier is characteristic of Guadeloupe, where it is quite a common female name, and France, where it is a very rare epicene name. Predominantly, Sannier is the last name as well as the forename.
