In Luke 2, Quirinius is said to be Publius Sulpicius Quirinius, legate Roman governor of Syria 6 AD to 12 AD.
Luke 2 (NRSV)
.
1 In those days a decree went out from Emperor Augustus that all the world should be registered. 2 This was the first registration, and was taken while Quirinius was governor of Syria. 3 All went to their own towns to be registered. 4 Joseph also went from the town of Nazareth in Galilee to Judea, to the city of David called Bethlehem, because he was descended from the house and family of David. 5 He went to be registered with Mary, to whom he was engaged and who was expecting a child ...
8 In that region there were shepherds living in the fields, keeping watch over their flock by night. 9 Then an angel of the Lord stood before them, and the glory of the Lord shone around them, and they were terrified. 10 But the angel said to them, “Do not be afraid; for see—I am bringing you good news of great joy for all the people: 11 to you is born this day in the city of David a Savior, who is the Messiah, the Lord.

Aspects of Luke 2:1-3/4 and 2:8-10 seem to align with aspects of Plutarch's Life of Romulus (other aspects of which also seem, in turn, to also have parallels with other aspects of the Gospel narratives eg. references to a spear being used in accounts of what essentially was/were epilogues to the crucifixion).
Life of Romulus (chapter 27 & 28 [1]-[2] are included for context)-
27 [4] ... Romulus disappeared suddenly, and no portion of his body or fragment of his clothing remained to be seen ... some conjectured that the senators, convened in the temple of Vulcan, fell upon him and slew him ... [6] Others think...that he was holding an assembly of the people outside the city near the so-called Goat’s Marsh, when suddenly strange and unaccountable disorders with incredible changes filled the air; the light of the sun failed, and night came down upon them, not with peace and quiet, but with awful peals of thunder and furious blasts driving rain from every quarter, [7] during which the multitude dispersed and fled, but the nobles gathered closely together; and when the storm had ceased, and the sun shone out, and the multitude, now gathered together again in the same place as before, anxiously sought for their king, the nobles would not suffer them to inquire into his disappearance nor busy themselves about it, but exhorted them all to honour and revere Romulus, since he had been caught up into heaven, and was to be a benevolent god for them instead of a good king. [8] The multitude, accordingly, believing this and rejoicing in it, went away to worship him with good hopes of his favour; but there were some, it is said, who tested the matter in a bitter and hostile spirit, and confounded the patricians with the accusation of imposing a silly tale upon the people, and of being themselves the murderers of the king.
[28] [1] At this pass, then, it is said that one of the patricians, a man of noblest birth, and of the most reputable character, a trusted and intimate friend also of Romulus himself, and one of the colonists from Alba, Julius Proculus by name, went into the forum and solemnly swore by the most sacred emblems before all the people that, as he was travelling on the road, he had seen Romulus coming to meet him, fair and stately to the eye as never before, and arrayed in bright and shining armour.
[2] He himself, then, affrighted at the sight, had said: ‘O King, what possessed thee, or what purpose hadst thou, that thou hast left us patricians a prey to unjust and wicked accusations, and the whole city sorrowing without end at the loss of its father?’
Whereupon Romulus had replied: ‘It was the pleasure of the gods, 0 Proculus, from whom I came, that I should be with mankind only a short time, and that after founding a city destined to be the greatest on earth for empire and glory, I should dwell again in heaven. So farewell, and tell the Romans that if they practise self-restraint, and add to it valour, they will reach the utmost heights of human power. And I will be your propitious deity, Quirinus.’
[3] These things seemed to the Romans worthy of belief, from the character of the man who related them, and from the oath which he had taken; moreover, some influence from heaven also, akin to inspiration, laid hold upon their emotions, for no man contradicted Proculus, but all put aside suspicion and calumny and prayed to Quirinus, and honoured him as a god ...
[29] [1] To the surname of Quirinus bestowed on Romulus, some give the meaning of Mars, others that of Citizen because the citizens were called Quirites; but others say that the ancients called the spear-head (or the whole spear) ‘quiris’, and gave the epithet Quiritis to the Juno whose statue leans upon a spear, and the name Mars to a spear consecrated in the Regia, and a spear as a prize to those who performed great exploits in war; and that Romulus was therefore called Quirinus as a martial, or spear-wielding, god.
[2] However that may be, a temple in his honour is built on the hill called Quirinalis after him, and the day on which he vanished is called People’s Flight [shades of the Ascension of Christ(?)] ...

Could the Quirinius of Luke 2:2 be a composite of Publius Sulpicius Quirinius and Quirinus and Romulus Quirinus? - with Quirinius used to anchor the story to the first few yrs of the 1st century AD?
