Coster Name Meaning
English: metonymic occupational name for a grower or seller of costards (Anglo-Norman French from coste ‘rib’) a variety of large apples so called for their prominent ribs. In some cases it may have been a nickname (from the same word) for a person with an apple-shaped (i.e. round) head. Dutch and German: variant of Koster and in North America (also) an altered form of this.
