Inheriting epilepsy?

I was told my epilepsy wasn't passed down to me even though my mom is epileptic too. She was hit in the head with a glass milk bottle; that is what made her have seizures. My brother also had seizures but his were at a very young age and they just stopped by the time he was 7. It seems there may have been a genetic trace but no one has proven it. I would love to know of more strange cases.
