FWIW, the Wiki page on DA14 shows it to be about 11 degrees inclination from the solar plain, and an orbital period slightly less than earth, and next encounter not till 2046*, so if that is the case then DA14 at least would probably be common to the asteroids of this solar system.

(*but it would seem that such a close pass to earth might have knocked it quite a ways off of its previous pattern, but I have not seen any data about the current adjusted trajectory, because they already admitted a few days earlier that their calculations were off, so previous calculations of future trajectory must then be off by even more.)

I am still curious though of the orientations of the various meteors seen within a few days of the 15th.
