This might be the song you're looking for. It was passed down to me from my Uncle. I'm not sure if the tile is right.

SNOWBALL TREE

They were very, very happy. Their marriage was a gem;
But death was soon to take his pretty wife away from him.
With her dying breath, she whispered, "We'll have everlasting love
And I'll come back to be with you as a little snow-white dove."

Time went by and nothing happened. The dove did not appear.
The young man fell in love again and married in a year;
But the day he brought his new bride home, the neighbors were to see
A snow-white dove come fluttering down upon the snowball tree.

There she sobbed and moaned, heartbroken in an almost human way.
No matter what the weather, she would perch there every day.
When the neighbors and the servants, yes, the story they had learned,
That in the guise of this white dove the young wife had returned.

The new bride heard the story, and her nerves began to fail.
The young man tried to help her, but it was to no avail.
To save his second marriage, he knew something must be done;
So at dawn the next morning, he went out with a gun.

He raised the gun and fired through the leaves so deep and green.
The snow-white breast turned scarlet and he heard a woman scream.
The dove flew high into the air and disappeared from sight;
But as he lay in slumber, the young man died that night.

'Neath the snowball tree, they buried him, to live in last repose.
The young wife and the servants left, for where nobody knows.
Now the big house stands there empty and the garden lies in ruins;
But above the young man's grave each year the snowball tree still blooms.

They say that no one comes to see that lonely unkempt green,
But every year at a certain time a visitor is seen;
And if you spoke to the neighbors, then they'll tell you what they see:
A snow-white dove with a scarlet breast perched on the snowball tree.

There sobs and moans heartbroken in an almost human way.
No matter what the weather, she will perch there every day;
And seems forlorn and lonely for a love that couldn't last;
And you hear her cry in anguish for a sad and tragic past.
Yes, the story of the snow-white dove has been told to you at last.
