With a little perseverence I was able to find much more information about Petra and the Nabateans.
The popular king name Aretes not only indicates devotion to Horus/Heracles/Herod (as a sun-god) but also to Re/Ares. The popular king name Obodes indicates a devotion to Obed/Solomon. The popular king name Ra-bel/Rabbel indicates a devotion to the god Re as the deliverer "Moses".
The following links provide more evidence of association with Parthia, the Hasmoneans, and the later Herodians.
