Even Bernhardt Fritz (Frids), Forgyller - Fritz / Frids / Frisch ?

Hello.
I have heard from relatives that our family in Norway was involved in the silver trade in Kongsberg and Oslo and wondered if we were related to the well-known Frisch family of Norwegian silversmiths. While Forgyller translates to craftsman, I have seen other documents listing Even Bernhardt Fritz as a Gelder (goldsmith ?) and wondered if there is a connection there.
Any information would be appreciated.
Thank you,
Juliette
