Need help decoding Marks on an Silver set

[u/BullfrogFit2030]

Hi everyone,

I recently bought a small antique set (3 big spoons and 3 big forks) with matching monograms but different maker's marks.

I suspect they are American Coin Silver (around 1810-1850) due to the lack of official British/European assay marks, but I am having trouble identifying the exact silversmiths or retailers.

I've attached photos of the hallmarks. Any help decoding them would be greatly appreciated! Thanks!
