Appears there is a likely genetic disorder afflicting several of your family members. This may well be a very uncommon mutation, and would require possibly the skills of a medical school geneticist to sort out. Would recommend Johns Hopkins School of Medicine or Mayo Clinic. We have numerous medications to handle epilepsy and migraines. An experienced neurologist could help. All the best.
