Daughter - Megan Ashleigh
Son - Hayden Michael
And no, we didn't get the name from the actor playing Anakin/Darth Vader, we got it from Hayden Fox on the TV show Coach.
But, Megan was almost named Rhiannon (after the Fleetwood Mac song). I always thought that it was pretty, but decided to give her a name that she could find on things...unlike mine...
I edited to add that had Hayden been a girl, we had decided on Kylie MacKenzie (it means daughter of the great leader, so DH liked that).
