There is a listing of groups in Deleware at http://www.witchvox.com/vn/gr/usde_gra.html
Not all groups advertise on Witchvox. So I'd also suggest checking out any local metaphysical shops (also listed on Witchvox) and any open Pagan events (listed on Witchvox too) as these can be good resources for finding groups in your area that suit you. Remember too that there isn't a coven in every town. But if you find a group that is aq good fit for you then driving a couple of hours to train and work with them is well worth it.
I found that Coven of the Rowan Star is located quite close to me- I am inquiring about the steps in joining, and better yet, seeing if that is something I want to do.
