Did he work for a firm, or on his own.
Does anyone continue his legacy in our times?
No
On his own business - citienship means that he established himself as a merchant, or other business - in this case as a Silversmith
No

The book list a lot of known silver from his hand. It does not say how many people he employed.
At the pictures you see Table silver continued at picture two. Then Church silver and finely Laugs silver (Guild silver) I would say that the list is very long. But part of that is the timeframe. Dead 1843 that is close to our times, so the silver has survied.
A silversmith fra 1740/1750 their silver has been recycled when it later came out of facion.
