Howdy johnk,
From my copy of "900 Miles: The Ballads, Blues, and Folksongs of Cisco Houston" which is an Oak Publication with a 1965 copyright, here are the words to the haunting song you've asked for.

THE GIRL IN THE WOOD
Traditional

When I was a young boy and drove my mother wild,
I met a maiden in the wood, and she said, "Child,
Look deep into my green eyes and at my autumn hair,
When you're a man you'll never see another quite so fair."

"Remember me, remember me,
Remember for the rest of your life."

Her eyes were green as grassy pools looking right at me,
And her hair was red and grown with leaves just like an autumn tree;
She moved her tiny hands and she made a little turn,
She swayed in the wind just like a gentle fern.

I swore as she vanished that when I was fully grown,
I'd have a girl just like her to be my very own,
And now I am a man and I'd marry if I could,
But I can't lose the memory of the girl in the wood.

I've wished a hundred times that she'd never looked at me
With the first wild beauty that only youth can see,
For a man cannot find it when he's looking for a wife,
And he'll end up in bachelor hood the rest of his life.

Allinkausay,
Bill^^
