Overwintered onions

Last year I planted a row of onion sets. Ate about half of them as spring onions and left the rest in the ground to harvest as dry onions in the fall. They went dormant in late summer, then just as I was ready to dig them in late fall they sprouted again. So I left them in the ground.
They came up again about a month ago -- in little bunches. Today I dug two of 'em to see what I had, and was surprised to see each was now 5 or 6 bulbless onion plants with lots of roots. They look kind of like scallions but stockier. I expected a golf ball- to tennis ball-sized rotten onion with sprouts in the middle. (Maybe if I had dug them a month ago they were rotten onions.)
I'm thinking I should divide these and plant them again? Do you think they will bulb, or will they try to bloom?

They are going to bloom. Use them as scallions/green onions.
Don't wait too long. The central flower stalk can get tough, though not a tough as in a wintered-over leek.
