I have a set of fiddleback spoons which belonged to my great-great-great? Grandmother. We can not find the marks anywhere on the web but think we have determined that the'D' means silver of at least 900. Not sure about the 6 pointed star unless it indicates imported. The left facing silhouette is male. She was born in 1790, married late and so aquired these from 1810-1830. Any help would be appreciated.
