Help with Maker's Mark -- W&D

[hpidaves]

This 9" coin silver serving spoon bears the mark "W&D", but I cannot find the maker with that mark.
Any help is greatly appreciated.

Thanks,
Dave

Hi,

This is by Woodruff & Deterly (firm of Enos Woodruff and Jacob Deterly) of Cincinnati, working circa 1817-21. More can be found on them online and in "Cincinnati Silver" by Amy Miller Dehan.

Best,
Cliff
