I'll be interested if you could determine the members of the councils by name . I know for a fact you you can't, so clearly you won't be able to provide any names.
Since there were several hundred present at the Council of Nicaea it is hardly surprising that all the names are not known. But a simple Wiki search reveals that a lot of names
are known. I quote:
"
Constantine had invited all 1,800 bishops of the Christian church within the Roman Empire (about 1,000 in the east and 800 in the west), but a smaller and unknown number attended.
Eusebius of Caesarea counted more than 250,
[20] Athanasius of Alexandria counted 318,
[11] and
Eustathius of Antioch estimated "about 270"
[21] (all three were present at the council). Later,
Socrates Scholasticus recorded more than 300,
[22] and Evagrius,
[23] Hilary of Poitiers,
[24] Jerome,
[25] Dionysius Exiguus,
[26] and
Rufinus[27] recorded 318. This number 318 is preserved in the liturgies of the
Eastern Orthodox Church[28] and the
Coptic Orthodox Church of Alexandria.[

Delegates came from every region of the
Roman Empire, including
Britain.
[29] The participating bishops were given free travel to and from their
episcopal sees to the council, as well as lodging. These bishops did not travel alone; each one had permission to bring with him two priests and three
deacons, so the total number of attendees could have been above 1,800. Eusebius speaks of an almost innumerable host of accompanying priests, deacons, and
acolytes. A Syriac manuscript lists the names of the eastern bishops which included twenty two from Coele-Syria, nineteen from Palestine, ten from Phoenicia, six from Arabia, etc., but the distinction of bishops from presbyters had not yet formed.
[30][31]
The Eastern bishops formed the great majority. Of these, the first rank was held by the
patriarchs:
Alexander of Alexandria and
Eustathius of Antioch. Many of the assembled fathers—for instance,
Paphnutius of Thebes, Potamon of Heraclea, and
Paul of Neocaesarea—had stood forth as
confessors of the faith and came to the council with the marks of persecution on their faces. This position is supported by patristic scholar
Timothy Barnes in his book
Constantine and Eusebius.
[32] Historically, the influence of these marred confessors has been seen as substantial, but recent scholarship has called this into question.
[27]
Other remarkable attendees were
Eusebius of Nicomedia;
Eusebius of Caesarea, the purported first church historian; circumstances suggest that
Nicholas of Myra attended (his life was the seed of the
Santa Clauslegends);
Macarius of Jerusalem, later a staunch defender of Athanasius;
Aristaces of Armenia (son of Saint
Gregory the Illuminator);
Leontius of Caesarea;
Jacob of Nisibis, a former
hermit;
Hypatius of Gangra; Protogenes of Sardica; Melitius of Sebastopolis;
Achilleus of Larissa (considered the
Athanasius of
Thessaly)
[33] and
Spyridion of Trimythous, who even while a bishop made his living as a
shepherd.
[34] From foreign places came John, bishop of
Persia and
India,
Theophilus, a
Gothic bishop, and Stratophilus, bishop of
Pitiunt in Georgia.
The
Latin-speaking provinces sent at least five representatives:
Marcus of Calabria from
Italia,
Cecilian of Carthage from
Africa,
Hosius of Córdoba from
Hispania,
Nicasius of Die from
Gaul,
[33] and
Domnus of Sirmium from the province of the
Danube.
Athanasius of Alexandria, a young deacon and companion of Bishop Alexander of Alexandria, was among the assistants. Athanasius eventually spent most of his life battling against
Arianism.
Alexander of Constantinople, then a presbyter, was also present as representative of his aged bishop.
[33]
The supporters of Arius included
Secundus of Ptolemais,
Theonus of Marmarica, Zephyrius (or Zopyrus), and Dathes, all of whom hailed from the
Libyan Pentapolis. Other supporters included
Eusebius of Nicomedia,
Paulinus of Tyrus,
Actius of Lydda,
Menophantus of Ephesus, and
Theognus of Nicaea.
[33][35]
"Resplendent in purple and gold, Constantine made a ceremonial entrance at the opening of the council, probably in early June, but respectfully seated the bishops ahead of himself."
[5] As Eusebius described, Constantine "himself proceeded through the midst of the assembly, like some heavenly messenger of God, clothed in raiment which glittered as it were with rays of light, reflecting the glowing radiance of a purple robe, and adorned with the brilliant splendor of gold and precious stones."
[36] The emperor was present as an overseer and presider, but did not cast any official vote. Constantine organized the Council along the lines of the
Roman Senate.
Hosius of Cordoba may have presided over its deliberations; he was probably one of the
Papal legates.
[5] Eusebius of Nicomedia probably gave the welcoming address.

Doesn't seem badly documented to me, for an event almost 2000 years ago.
