Plumeria is the name of a genus of flowering plants, also known as frangipani. It was named after French botanist Charles Plumier. The origin of the surname is uncertain though it could be related to French plume meaning “feather; quill” via Latin pluma (feather, plume) derived from a PIE root word. It may have originated as an occupational name for someone who worked with feathers. (*Plumier is also a French word meaning “pencil box”).
It’s also possible that Plumier is a variant of Plumer, an occupational name for someone who worked in lead or with lead pipes, from French plomb (lead).
