How do I start a Support group in my local area?

I am an estranged (alienated) mother and have met other mothers who have been railroaded by the family court justice system.There are no support groups in our area and I would like to start one as I have found many people are suffering the same injustice....Fathers, Grandparents, and siblings alike. I have found that just knowing that one is not alone in these experiences,helps greatly in the healing process.
