Question about punctuation

[luzula]

Here is a sentence with three variations in the comma placement:

1) It was not yet noon, and though it was October, Keith thought he might reach Ardroy that same day.
2) It was not yet noon and, though it was October, Keith thought he might reach Ardroy that same day.
3) It was not yet noon, and, though it was October, Keith thought he might reach Ardroy that same day.

I feel like 1) is the most common today and the one I would have used before my current fandom. But the 1925 book I'm writing fic for only uses 2) and 3), so that's what I am now using in my fic. I suppose 2) and 3) do make more sense in a way, because if you remove the phrase "though it was October" with its surrounding commas, you still get a sentence that works, which is not the case in the first one if you remove "and though it was October" with its surrounding commas.

My sample here is just one author, but I do wonder whether 2) and 3) are more old-fashioned ways of using commas?

There's different formats to punctuation, not necessarily strictly grammatical, whatever system you choose to use. I agree with the #2, with #3 correct but a bit excessive with commas.
But to test if it's just about intonation, try replacing 'though' with 'although'. To my ears, version 1 doesn't work with 'although', which suggests it shouldn't be right with 'though' either.

Huh, I think of "though" and "although" as having about the same meaning, so for me that doesn't make a difference! It mostly makes a difference in whether a word with one or two syllables fits better into the flow of the sentence.
