Why is there a comma in ", held in"? What is the difference between with and without comma?
Usually a comma is inserted to describe a farther thing, but this is describing the closest one, festival.
ex)Each year in Twinsburg, Ohio, the world's largest gathering of twins takes place. Thousands of sets of twins attend the festival, held in memory of Moses and Aaron Wilcox, the pair of twin brothers who gave Twinsburg its name......

1. (in blue): this gives us extra information about the festival. It (and the following words) could be omitted, and the sentence would still make sense. Non-defining.
2, (underlined): This gives us extra information about Moses and Aaron Wilcox. Ot could be omitted , and the sentence would still make sense. Non defining.
3. (In red): This tells us which twin brothers we are talking about. It cannot be omitted. Defining.
In the two non-defining clauses, the commas wcould be replaced by brackets. with the defining clause, there is no comma.
It would be possible to say and write #1 as a defining clause, with no comma preceding it.
Could a simpler explanation of the use of the comma in question be that in such a long sentence that's where the writer thought you'd want to take a breath if you were reading it aloud?
Well I'm not a grammarian, you see, and I doubt that more than 1% of native speakers know the difference between those types of clause (or care).
The important thing is not the labels, but the fact that there is a real difference in meaning between the two types.
