We show that a statistically significant number of Earth-crossing asteroids are part of the Taurid Complex of interplanetary objects. We also identify another group which appears aligned with (2212) Hephaistos. In addition, we describe the kind of orbital evolution that such asteroids undergo and consider the implications for the history of these two complexes, which may have a common origin.
