I've watched videos, looked at a zillion charts and cannot figure out what the castle, W or crown mean. It was my grandmother's and she lived in Newport, RI. She owned mostly sterling but had a few plated pieces. Any help would be greatly appreciated.
And, since I can't figure out how to add photos, the castle has bricks on it and is in a shield. The W looks like a trident and the crown looks a bit like a heart shaped beachball also in a shield.
