I'm posting this here in case anyone might know:

Several years ago, I watched a movie on TV that was based in England.  It started off at a funeral with a little boy and a little girl.  They went into the backyard, where the cemetary was, and met their ancestors (also a little boy and a girl).  The ancestors asked them to help them prevent the fire that took place where they were tied to a bed by their guardian and set on fire.  The little boy and girl went back in time and helped their ancestors get out of the fire, which gave them a chance to live instead of dying so young.  It was a really good movie, but I don't remember the name of it.  I think it was back in the 80's.  Does anyone remember it?  I'd really appreciate it!  Thanks!
