Here is what I think may be a variant of "The Old Oak Tree" as mentioned by Guest dgaldas. It was collected in Binalong New South Wales, Australia, by Rob Willis. It was sung for him, in 1991, by Val Turton (born 1927).

Liza Wells

Dark was the night, cold blew the wind, and heavy fell the rain
When Liza left her dear old home, to never return again.
She left her dear old mother's side, and she went out in the cold.
For she was young and sensitive and love had made her bold.

She heeded not the wind that blew, or the tempest raging o'er
She drew a mantle 'round herself, and boldly left the door.
The night passed on and the day passed on and Liza came not home
Which caused her dear old mother to say, "How can she roam alone?"

'twas in the scenery of some woods, where the owner of some land,
Squire Coleman and some of his gentlemen, were hunting with their hounds.
Over hills and down the dells all gallantly rode they
Until the hounds they all did stop beneath an old oak tree.

The hounds began to yelp and bark, and to yelp and bark did they
And all the whips those hounds did get could not drive them away.
The gentlemen they gathered 'round and they called for pick and spade
For they dug the ground and there they found the murdered mystery maid.

In her side they found a knife, and with a look of shame,
The gentlemen read on the blade young Squire Coleman's name.
"Oh gentlemen" Squire Coleman said, "My soul is fit for Hell
Oh hide me from that cold, cold corpse and the truth to you I'll tell.

I know she loved me dearly, and from me would not part
And in my selfish, wicked way I knew I'd won her heart.
She pleaded me, tormented me, tried me make her my wife
And the Devil whispered in my ear, "Why don't you take her life?"

And with that knife found in her side I pierced her snow-white breast
Oh, gentlemen", Squire Coleman said, "Why need I tell the rest?".
He knelt down by the cold, cold corpse, and with a look of pain,
He drew a pistol from his belt and fired it through his brain.

And where he died they buried him. No Christian grave got he
No marble stone to mark the place beneath that old oak tree.
