Hmm, the only thing I see connecting the dwarf to the other characters is Orcrist.
So, maybe they all had something made in Gondolin.
Thorin with Orcrist.
Galadriel with the Elessar.
Tuor had... Idril? Or something else, he did live there after all.
And Maglor...bah, no idea at all there.
EDIT: somehow I feel Lommy is correct.
