I don't know if this is relevant since this reply is to a post from 2009, but I have Wilce in my family tree. I have been able to trace the lineage back to a Thomas Wilce born 1599 in Dymock. His father was John Wilce, but that's all I know about the father.

Obviously, researching back in time this far is often more about subjective interpretation than solid facts, so there's no guarantee to the information I've got.
