Your piece is called a portrait plate , her name is unknown, I can tell you it is a portrait decal and was used on wares by Nippon. Is your plate Nippon I doubt it the boarder is not painted elaborately enough. I would search portrait plates on ebay and such but look for the same plate shape & decoration painted (on the edge) and you will probably find the company. One German firm C.S. Pocher, circa 1900- 1915 made these decals and sold to many factories for them to use on their wares. Here is a small photo of a Nippon plate with your portrait decal from Nippon Porcelain 6th series.
