Yvonne is a feminine given name, the female form of Yvon, which is derived from the French name Yves and Yvette. It is from the French word iv, meaning "yew" (or tree). Since yew wood was used for bows, Ivo may have been an occupational name meaning "archer". Yvonne/Ivonne is also a Spanish girl name. This name first arrived in England with the Norman invasion, along with variations such as Yvette and male versions of the same name. It was the most popular of all of these names, but would fall out of favor.
