I had never heard of Goibniu but he is easily googled and seems to be a kindred spirit to Vulcan and Wayland. We recognize "Vulcan" as the name of a planet in Star Trek and "Wayland" as the name of a planet in Poul Anderson's Technic History.
Blacksmith gods were important when blacksmiths were important and that technological level returns in SM Stirling's Change/Emberverse series. "Smith" is the commonest surname in England and "John Smith" is the commonest name.
