I know his death had something to do with the Lodges and his backstory would be an incredible fanfic if done properly.  What are your thoughts on this mystery?

He was a lumberjack/firefighter who died in a fire on their wedding night. And he has something to do with the black oil in Glastonbury Grove. Yeah, there's a story there somewhere.

Honestly I think way too much attention is given to the log, I don't really see any reason why her husband couldn't have died in a fire. It was a classic, quirky, and funny way to dispense red herring clues and then they decided to have the lodge give information about the lodges so that they could use the Log Lady again... Margaret's probably just one of those people that have visions concerning the Lodge and it's inhabitants, like the Palmer family, and that's how she knows things... The real question in my opinion is whether she actually thinks the log gives her information or if it's her way of distancing herself from the townspeople.

I wonder if her husband stumbled onto something he shouldn't have like Glastonbury Grove or the spirits got to him because of the Log Lady.  Is his spirit trapped in the log now?

There are many indications that Mr. Lanterman didn't die in a normal fire, just check what is said and what the Log Lady prefers not to say in the scene at her cabin or look at one of the Log Lady intros (written by Lynch): "My husband died in a fire. No one can know my sorrow. My love is gone. Yet, I feel him near me. Sometimes I can almost see him. At night when the wind blows, I think of what he might have been. Again I wonder: why? When I see a fire, I feel my anger rising. This was not a friendly fire. This was not a forest fire. It was a fire in the woods. This is all I am permitted to say."

Add to that the many references Margaret makes to "that kind of fire", that she heard the call of the owl when her husband died and that he knew about Glastonberry Grove and the oil and the conclusion is that he was a victim of something evil, not necessarily an entity like BOB, but with the same origin... Besides, I believe that, like Laura, he *knew* he was going to die or better he chose to die to protect Margaret and get rid of the evil... Hints of this is that he died the day after they got married, like if he wanted to before going, and that he gave her the oil just before dying...

Another reference to that kind of fire:

In FWWW, Margaret touches Laura's forehead and says: "When this kind of fire starts, it is very hard to put out".

Plus there was going to be a scene with her tattoo going beet red whilst she howls to the moon. This is all during a time of Lodge intervention.

 I read a cool fanfic wherein The Log Lady noticed someone drinking coffee and remarked how she detested it, and how it "made [her husband's] hair turn grey." Now in terms of unofficially expanding the storyline, I'm not opposed to it; the exposition is actually interesting, I'm just not of the idea that BOB was ever corporeal.
