Kane and undertaker are not related in real life
No because Kane or Glen Jacobs and Undertaker or Mark Calaway are not even brothers that was just a storyline.
They aren't brothers so they don't have the same mom.
no Kane killed her, well it was a fire, but Kane started iit.
There has never been a mention of The Undertakers mother on WWE television.
Because undertakers real brothers name was Kane
The story is, Kane and the undertaker were playing with matches and Kane accidently burned down the house killing his mom and dad. The undertaker felt responsible for this because he was the oldest and should've known better. Paul Bearer (the undertaker's manager) made the undertaker believe that he burned it down and the undertaker admitted that he did but he didn't. The undertaker thought Kane was dead after the fire but the Kane interfered in the undertakers match with shawn michaels for the first time. Taker looked at Kane confused and Kane delivered a tombstone piledriver. And that's the undertakers childhood story. (:
