Well you have the people of the
Sable Mole, whose
Maeglin was their leader, and they fought with
axes two-headed like mattocks so you can discount those of his house.
You have too the
Folk of the Swallow whose leader was
Duilin, but they used
bows, so you can discount him too.
There were also those of the
Heavenly Arch, and whose leader was
Egalmoth, they used
swords and bows, but his
sword was bent -- now none else of the
Noldor bore curved swords, so you can count him out.
You have the host of the
Pillar and of the
Tower of Snow, who were led by
Penlod. I don't think that it specifies if they used some kind of different
weapons, but I would guess that they used swords.
We have also those of the Tree, led by Galdor, but they used iron-studded clubs or with slings, so you can discount him too.
You have those of the
Golden Flower, whose leader was
Glorfindel. I don't think it specifies that he used a sword, but from LOTR, he uses one, so I assume that he wields a sword unless I have a reference that contradicts it.
There is the People of the
Fountain, whose leader is Echtelion, and he used a sword.
Those of the
Harp, whose leader was
Salgant, i think that if otherwise proven, he used a sword.
Then they were those folk of the
Hammer of Wrath, whose leader was [Rog], and they used "great maces like hammers", sounds familiar?
There are those of the Emblem of the
White Wing, whose leader was
Tuor, but he used an
axe.
There were also the folk of the
Royal house. They stood with
Turgon until the end, and since the swords were mates, I would venture to guess that it must have been used by one of Turgon's Royal House.
