Morning Richard
You should first take a look at-
www.familysearch.org

simply entering the Last Name-
foree

and selecting-
Exact Spelling

A number of Forees come up for Cork; but Charitee is not amongst them.

Judging by the responses for Continental Europe, the name has South Dutch connections, which may link it back through Belgium to France and the Huguenots.

Regarding the Silversmith aspect, if the name "Foree" was directly engraved, this suggests "family silver" rather than "silversmiths"; but I may be wrong.

Go to-
www.google.com

Search for-
+"foree" +silversmith

None appear to be recorded in Web sources as silversmiths; but there is a response of interest, the Pigot Directory for Cork 1825, contains a Foree - plumber.

So at least there is a metalworking connection; and silver ore is often found with lead ore.

You may have to pursue locally-held records in Cork, to obtain more information.
