In the Pines (Black Girl)
and
In The Pines from the Kossoy Sisters.

The first definitely has the dead man as "father." The lines

"You caused me to weep, you caused me to moan
You caused me to leave my home"

coupled with

"The longest train I ever saw
Was a hundred coaches long
And the only boy I ever loved
Is on that train and gone."

Lead me to think the "you" is the boy, and he killed her father and took off on the train. Of course, the boy may have left town out of fear.

Here's a question: If the girl knows the father/daddy got killed a mile and a half from town, AND he was killed in a train accident, his body, or bits of it, should have been found. In other words: location of death known, location of body, unknown.

The second has no murder/death, but has a man singing about a woman who's apparently in love with some guy who lives out in the woods and gives her dresses.

I'm not so sure about cemetaries and pines - I haven't noticed a connection. Pines are all over the place where I live. It sounds more like a pine forest to me - especially since the girl says she's going to go live there. Steve, do you have any information on the history of the song?
